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

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.

Sorry, but I don't agree. I've had very good luck with them.

Re: Brake fluid LEAK!!

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

Same here, only had a couple experiences with them and they were all good.

My only complaint was lack of ANY instructions with a disc brake conversion kit we bought once - just a box of parts and a bag of bolts! LOL! I wasn't impossible, but with a straight axle kit, there's a combination of spacers to figure out.....

Re: Brake fluid LEAK!!

I bought a disc brake kit for my Camaro, and had the exact same issue. Can't remember who made it or where I bought it. When I called, they said, "the vendor who rebuilds those for us has had some quality issues lately." Wow, thanks. I didn't have patience for the send it back then send me another (that also might leak). So I bought a seal kit at the local parts store, a hone, and rebuilt it myself. At least then I knew it was right.

I might have to do the same thing, sent an email yesterday and still no response.

Re: Brake fluid LEAK!!

That's why I prefer to buy as many of my parts as possible local. I don't have to ship back and forth for warranty issues.
