Brake fluid LEAK!!

I bought a CPP brake booster master cylinder kit to go with their disk brake kit. Can someone tell me what would cause it to LEAK between the MC and Booster? I can't stand leaks and of course the fluid ate up my Por-15 on the frame. Please help.

Thanks
Rudy

Re: Brake fluid LEAK!!

The master cylinder is defective- the rear seal is bad.

I'd be on the phone pronto with them if you recently purchased it.

I'll be on the phone first thing in the morning, thanks. At first I was think the brake rod might be too long.

Re: Brake fluid LEAK!!

i was told by a senior forum member that DOT 5 brake fluid wont eat the paint, but you have to only run that kind once you switch as its not compatible.

I didn't think anything but a hammer would damage POR15!

Re: Brake fluid LEAK!!

I just sent an email to Mario @ CPP, explaining the issue with pics. Lets see how they handle it.
