DETAILS

The PERRIN Master Cylinder Brace eliminates the flex at the firewall by bracing against the solid shock tower so you feel nothing but solid pedal feedback with every application of the brakes. Even slowing for a stop sign, the difference can immediately be felt after installation of the PERRIN Master Cylinder Brace.

The PERRIN Master Cylinder Brace is constructed of CNC Machined 6061 aluminum, and CNC formed Steel. This combination of different materials are used to add extra support compared to other systems. Making this from two CNC parts instead of a series of welded steel pieces, keeps the part extremely stiff as well as very light.

They constructed this part to bolt to three different surfaces around your shock tower. One surface runs parallel to the master cylinder, one perpendicular and another perpendicular but on a different plane. Triangulating the mounting points reduces flex even further than single plane designs.

The aluminum portion is anodized black with a bold PERRIN logo laser engraved into the upper surface. The steel section is wrinkled powder coated in your choice of three colors to match your other PERRIN parts. Perfectly combines an aesthetic improvement to your engine bay as well as better braking feel!

Simple but effective

This is a very simple mod that definitely forms up the brake pedal. I will say it doesn’t affect street driving much if at all, but it’s definitely noticeable under very heavy braking.

Please be careful during install. It’s a very tight area and there is a high likelihood you will drop something if you’re not careful (like me). Not a fun part of the engine bay to lose something in.

Also please see the photo I’ve attached. There’s a lot of YT instructional videos that are incorrect. Perrin’s instructions say to tighten the jamb nut to the Master Cylinder Brace, NOT the Master Cylinder. Most images I’ve seen show jamb nuts tightened in the wrong direction, doing nothing.

Great product, high quality, worth it if you track the car but probably not otherwise necessary.

Joe,

Thank you for your 5 Star Review! We appreciate your insight on the improved brake pedal feel, especially under heavy braking. The tight installation space can definitely be tricky, and we appreciate the heads-up about being careful not to drop anything. Your note about instructional videos is helpful as well. Enjoy the upgrade!

Definitely works under heavy braking

First off lemme say you need to be mentally prepared for how deceptively difficult the install is. I’ve been wrenching for 15 years but that doesn’t make me immune from a curse fest when I drop a bolt in the engine bay because the work area is too cramped.

But that’s not a knock on Perrin. The part, once installed definitely firms up the brake pedal noticeably under heavy braking. At low speeds/moderate braking I didn’t notice much difference. But it’s more important under heavy braking anyway.

Very happy with this simple little device.

Joe,

Thank you for your 5 Star Review! We appreciate your detailed feedback and are glad the brace performs well under heavy braking. We understand the install can be challenging, but your expertise and patience paid off. Thank you for your support!

Tight squeeze

Installation was a little annoying being a tight squeeze but not too bad. Overall not really sure if i do notice a huge difference on braking but there is definitely a difference!

Perrin master cylinder brace

This little engineering miracle not only firms up the brake pedal feel but the clutch release feels better leading to smoother shifts overall.

Justin,

You are absolutely right! The Perrin Master Cylinder Brace is a small piece that does an unbelievable amount of work! Not only does it firm up the clutch and brake pedal but it keeps your firewall from flexing and the welds from cracking! We appreciate your 5 Star Review!
