BlackPath’s Caliper Kit allows the installation of larger 300ZX calipers and 12.75″ 350Z rotors (not included) on your Nissan Maxima. The bracket is made for a 240SX but also fits your 4thgen or 5thgen Nissan Maxima.

Important Note: You will need the 350z Front Rotors which are 12.6″. Not the 12.6″ 6thgen Maxima Rotors or the 13″ Cobra. You will also need the 240SX to 300ZX brake lines.

Part Name: Compact Remote Combination Master Cylinder Kit
Part Number: 260-10374
Price: $83.00
Order Link: https://www.summitracing.com/parts/wil-260-10374

Important Note:

The inlet for the clutch line is a 1/8-27 non-inverted flare. So usual regular SS one-piece lines won’t work as-is. You’ll need a SS line made along with a 90-degree adapter. That is pretty easy to get made locally so you won’t have to use any special conversion adapters.  Also, there is no need for slave cylinder rod spacers because this pushes plenty of fluid. 

 

Wilwood Compact Remote Flange Mount Master Cylinder

90-Degree Adapter with Custom One-Piece SS Line

Product Info

Wilwood’s Compact Combination Master Cylinders have been designed for limited space applications requiring the output capacity of a full size master cylinder. The ultra short 3.37”compact body provides 2.16” of additional clearance between the mounting flange and the fluid outlet. A full 1.12” of piston stroke meets or exceeds the stroke capacity of most full size cylinders. With 1/8” NPT fluid outlet port located at the top radius of the cylinder bore, reduces the chances for trapped air. Enhanced fluid inlet port allows mounting of the standard reservoir included in kit and also contain 11/16-20 internal threads for custom reservoir arrangements. The black E-Coated aluminum body resists corrosion and maintains a durable long lasting finish.

Until someone can TRULY engineer perfect Akebono brackets that bolt on to front Altima with zero modding needed, I only recommend this to people who are mechanically inclined, are willing to DIY, and go through some trial and error and use your intuition. Z1 motorsports 300ZX Z32 to Akebono adapters totally work but only for the DIY-enthusiast willing to modify them and spend some hours in the garage. Caliper lugs have to be shortened 6.85 mm to almost flush with the bracket. Also sleeving 14 mm bolt hole for 12 mm bracket bolts. Plus grinding a recess in the bracket for CV joint clearance.

Z1 Motorsports Akebono Front Brake Bracket Kit (300ZX)

Description: The Z1 Motorsports Akebono Front Brake Brackets are intended to mount the Sport model, Akebono Brake Calipers from the ’09+ Nissan 370Z or ’08+ Infiniti G37 Sport onto your 300ZX.

Each Z1 Akebono Brake Bracket Kit includes two black, hard anodized aluminum front brackets and all necessary hardware to properly install the calipers onto your ’90-’96 Nissan 300ZX. Designed and tested extensively in house, these are the best brackets on the market with the most even pad sweep. Our unique single piece design also makes installation a breeze. In addition, the one piece bracket design also means our brackets are more rigid than other pieced together kits on the market. These brackets do not require any additional machining or modification of the caliper itself in order to complete the installation.

Installation & Write-up

Rear is perfect install on knuckle with NO ADAPTER needed. No fuss no muss. You need the rear 370Z akebono calipers, rear 370Z rotors (I got Centric 120.42101 blanks), rear 370Z pads (I got Carbotech 1521 pads), Altima Stainless Steel Lines and you must specify the Akebono banjo bolts for these lines!

Perfectly centered, no shims necessary.

All 4 brackets were spaced for rear. Returned them and bought the Z1 adapters.

Z1 300ZX Z32 to akebono adapters. Quality 1 piece design. Altima front mount is 14mm and 300ZX is 12mm so some modding will be needed.

Re-drilling and tapping from 12 mm to 14 mm requires precision fixturing for diameter control as well as perpendicularly to existing holes, something I can’t do at home. Therefore I’ll sleeve the knuckle lugs with 1 mm shim stock coiled into a split bushing to eliminate any slop when mounting the adapters with 12 mm.

Axial positioning of calipers is outward approximately 1/2 inch. The alignment would probably be right on if the adapter thickness positioned calipers at the original lug surface. I suspect the 300ZX knuckle had a different offset.

Caliper lugs have to be shortened 6.85 mm to almost flush with bracket. Some other people who had issues with mounting 300zx brackets said they needed a few washers to space out the bracket from the knuckle and shave the top crevice of the caliper for the rotor to spin free A few washers adds up to what I did. I ended up using two slightly thicker OEM caliper bolt washers (6.85 mm total) and it seems to provide perfect centering

Sleeving 14 mm bolt hole for 12 mm bracket bolts. Plus grinding a recess in bracket for CV joint clearance. Should fit even better

At the local fastener store and got automotive grade revised bolts (didn’t have the proper lengths on hand)
Some pad overhang is negligible and at the pad is at the OD where it belongs. Swept area doesn’t cover full rotor radial which must be by design and still has massive capacity that will not get hot unless you’re at the track.
For front rotors, I am using are Lancer EVO X Centric High Carbon rotors which are 13.78 inches instead of 370Z’s 14 inch. There was controversy that 370Z rotors wouldn’t fit so I got the Mitsubishi ones. Doesn’t matter, they are same thickness and everything just 0.2 inches less diameter – never gonna make a difference.
Finally got the fronts centered and mounted. Had a problem with bracket interfering with caliper reinforcing rib when torquing down final assembly and had to disassemble and do more minor bracket mods.

1) Loosen the lug nuts on the wheels corresponding to the brake pads you are planning to change.

2) Jack up the car (refer to How To for examples).  Make sure you use wheel chocks and do not engage the emergency brakes.

4) Lay out your new brake pads (and new brake kit if you ordered a new brake kit. The brake kit includes new shims in case your old ones are cracked or worn. But, I’ve seen others’ who were cracked pretty bad. It’s up to you whether or not you want to pull things apart and discover things are cracked and then go get a set, or get it anyways. In my case, I could have stuck with the old set).

In this picture, the two pads are in the center of the picture, then going outwards, are the two shims that came with the aftermarket pads, then the two stock shims that come with the brake kit (or were there with the stock pads), and then the outside is the stock angular shim, and then finally, the small bracket that goes on the top of the pad assembly. I ended up using the aftermarket shim instead of the grilled stock shim. The aftermarket shim had adhesive on one side to stick to the back of the pads. (If your new brake pads only have one of the two pads with a wear indicator, put it on the inside of the caliper).

This is how your shims should look when assembled onto your new pads :
Brake Pad Side (you can see the small ‘assembly’ bracket at the top of the pad backing)

Backside of brake pad, with shim, angled shim, and then the small ‘assembly’ bracket.

5) Remove the cap of your brake fluid reservoir off, and put some towels around it in case of overflow of brake fluid.

6) Turn the steering wheel so that the front of the brake caliper you are working on, is facing you as much as possible.

7) Remove the spring that hooks into the holes in the top and bottom pins. Use your fingers or a pair of needle nose pliers.

8) Using needle nose pliers, push from the inside on the pin and pull from the outside with your fingers. Remove the top pin. However, pull the pin out slowly and brace your fingers against the flat spring that will want to launch out at you.

9) Then remove the bottom pin and the metal spring will fall out easily.

10) Grip the brake pad backing and pull it out (this will remove the brake pad and all it’s shims). If it is tough to pull out, try wiggling it slowly by pulling a bit on the top part and then a bit on the bottom part. Remember to pull out both the inside pad and the outside pad on either side of the rotor.

11) When removing the pieces from your caliper, lay them down on the ground so that you will remember how they go back. Here’s a picture of what I did as an example.

This is what your caliper will look like with the pads out.

12) Now, if the old brake pads were quite worn, you will have difficulty in getting the new and THICKER brake pads back into that little space. This is where you’ll have to push back on the pistons to make room. And this is why you removed the cap of the reservoir in case a lot of brake fluid gets pushed back up the system and overflows your reservoir. See the picture below, the shiney part is the piston and surrounding it is the rubber dust boot. You want to make sure to NOT damage the rubber dust boot and just ‘squeeze’ the piston back into the caliper.

This is my favorite ‘persuader’ tool. Got me out of a fix when I once overtightened my oil filter.

You should put tape around the persuader, or put cloth against the caliper if you are afraid of damaging the finish on the caliper. Firmly and slowly squeeze the pistons back in. You’ll notice a see-sawing effect. As you squeeze one piston, the others will have a tendancy to come out a bit. But, just alternating squeezing the pistons will bring them all deep enough to fit in the new pads. Just go round and round squeezing the pistons until you have enough clearance.

13) Do a dry run but assembling the brake pads (WITHOUT greasing it yet), just to make sure you can fit both new brake pads in without any clearance problems.

14) Ok, if you’re sure that BOTH new brake pads will go in, start assembling the shims onto your brake pad and apply the anti-squeal grease on the shim. The grease stuff is pretty toxic, I always use latex gloves when working with this stuff.

Assembled and ready to go? Then drop them back in and just reverse the disassembly procedure. Put the pad assembly back in the caliper. Place the lower pin in first. Place the upper pin partially in, and then put the metal spring in place and tuck the top part of the metal spring underneath the top pin and push the top pin across completely. Insert the small spring on the inside of the caliper and hook the ends of the spring through the holes in the upper and lower pins. Put the wheels back on. Put the lug nuts back in. Lower the car back to the ground. re-torque your lug nuts to spec.

My rear brake line on 4thgen Nissan Maxima had a pinch in it and caused brake fluid leak. I was going to  replace with another stock line but ended up ordering stainless steel brake lines from eBay. You get all 4 brake lines shipped for $67 bucks which is a great deal. The quality is great and serves its purpose well. Shipping took about a week since it came from Canada. After installing, I performed the brake bleeding procedure. Took a quick drive I can feel better braking overall with these lines.

Price: $67.32
Order Link: https://ebay.us/kptlZw
Description: You get 4 brake lines. 2 front and 2 rear.

Fits these cars:

  • 1995 – 1999 Nissan Maxima 4thgen
  • 2000 – 2001 Nissan Maxima 5thgen
  • 2002 – 2003 Nissan Maxima 5.5Gen
  • 2000 – 2001 Infiniti I30
  • 1993 – 1997 Infiniti J30

I finally decided to swap my rear Airtekk bags on my 2004 Nissan Maxima. The Airtekk Rear design is not great and rubs against the body of the car. Luckily, I was able to catch the issue before I go a leaky airbag on the highway. The Airtekk bags themselves are very slim and I couldn’t imagine getting an even smaller bag. Hopefully, they fix this in the future as every 6thgen Maxima would face the same. You would literally have to hammer the wall so much for the proper clearance (not worth it). The entire install took me around an hour.

Thanks to Rani and Ham for the info.

The Issue

 

The Replacement Bags

  • Rear Bags:  “Air House 2” By Universal Air Part # 02-2600 ($79 Each)
  • Rear Brackets: You will also need brackets for the rear. You will need to call as they are not listed on UAS Website. You need two sets and they are $69.00 each. So $138 for brackets.

The Install

You need to remove the Airtekk bag from the strut itself and keep it without the bag. Otherwise,  you don’t have a shock absorber and a terrible ride.

This is what the strut looks like installed. The top 2 bolts are 12MM.

Added some black rust paint to give it a fresh look and also take care of the rust.

Final Product

Car rides so much better. It also sits great. I can go lower in the rear but decided to match it up with the front.
