FAQs

What does it fit?

Q: I have a Mk1 chassis vehicle, what modifications or upgrades do I need to use your braking systems?

A: Our kits require the use of a 22mm master cylinder, and front knuckles with separate pad and caliper carriers. Our kits replace the caliper and pad carrier. The 22mm master cylinder originated from the Scirroco 16V, which is becoming hard to find. A popular upgrade is to use the Mk3 brake booster converted to run with the Mk1 pedal cluster. The modification involves cutting the booster pushrod and clevis pin from the Mk1 booster and welding to the Mk3 pedal cluster. After this, you can run the 22mm, 23.8mm and 25.4mm master cylinders.

Q: I have a Mk2 or Mk3 chassis vehicle, what modifications or upgrades do I need to use your braking systems?  

A: Similar to the Mk1 Chassis, our kits require use of a 22mm master cylinder, and front knuckles with separate pad and caliper carriers. Luckily, parts are not in shortage for this platform of vehicle. Most Mk2 and Mk3 VW's came equipped with the correct type of knuckle, except for some base platform vehicles such as CL models. They are easy to find used. The Mk3 22mm master cylinder bolts in to the Mk2 booster if you have an early Mk2.  

Q: I have a Mk2 or Mk3 chassis vehicle, what vehicles have the correct knuckles for me to convert to?

A: B3 and B4 Passat 4x100, Corrado G60 4x100, Corrado VR6 5x100, Mk2 GTi, GLi and GTX 4x100, Mk3 3 GL 4x100 pattern, Mk3 VR6 5x100

Note: it is recommended to replace the wheel bearings in any knuckles assemblies that are being reconditioned before installation. A little money spent here is well worth it. 

Fitment

Q: Is there any way to test if MMP's braking kits will fit behind my wheels?

A: We have templates available that you can request. You will have to print them to hard card, and use them to sweep the inside of your wheel for clearance. Please note that our templates must not be used for competitors brake kits, as ours are unique to our kits, and clearances will vary.

Q: I want to hide my braking system inside the cabin so I can have a smoothed/show engine bay. What components are required for this?

A: The basic components needed are a Wilwood pedal cluster (two pedal brake/clutch orthrdal), front and rear brake master cylinders, and a clutch master cylinder. The master cylinders will require either remote fluid reservoirs, or in some situations they are integrated. The pedal cluster is best to be dry fitted and mocked up before paint, when the vehicle is in the metal work stage. Please contact info@momentummotorparts.com before ordering so that the system can be designed and tailored for your specific needs.

Braking Performance 

Q: When picking piston sizes in my calipers, is bigger better?

A: Simply put, no. You can have too much front or rear braking. More isn't always better, sometimes it's just more.

There are many factors when it comes to braking system design. Caliper piston sizing is only one of many factors. "Clamping Force" is a term that is overly used in the aftermarket braking industry. Ask any professional racer, and they will always tell you that they want a brake feel that has modulation, predictability and a consistent feel. It depends on many factors. Mechanical grip, weight distribution, suspension setup to achieve this, driver feeling and feedback.
