Re: cpp booster kit disc/disc

I'm using that booster. Working just fine so far. CPP is the most popular MC/booster setup, I'm sure you'll be pleased with it.

Re: cpp booster kit disc/disc

Make sure to check the fitment of the master cylinder to booster, if it is too tight your brakes will lock after a short time driving , I have had this problem with 3 different cpp kits , 2 washers in between the master and booster are what is needed to correct it , cpp does not mention this in their instructions . Going from stock brakes to this system is a huge improvement . Im sure 60 to stop distance is cut close to in half

Re: cpp booster kit disc/disc

Yes I do. In fact I'm patiently waiting on my replacement from CPP. The booster leaked where the master bolts to it. The master cylinder has two plugs on the opposite side. the rear plug leaked brake fluid while I was bench bleeding it.

I had read there could be problems with the booster leaking but had not seen any posts on the master cylinder. Both of mine failed.

Stay tuned and I'll let you know if the replacement booster works. I've already purchased another mastercylinder so I won't be using the replacement when it arrives.
