Rear Caliper Rebuild Serious Problem!
Posted: Fri May 06, 2005 1:11 pm
My Personal 1985 GTV6 sat for a full 12 months while it served as a jig to make the supercharger kit. As we all know that's really bad for all the hydraulics. Since I put it back on the road, every couple months something hydraulic seems to fail. Up until now that's not been a big deal since I fully expected it. Not a problem that is until a rear caliper started leaking.
Now I have a real problem. I am wondering if anyone else has had this one. The right rear caliper is leaking from the internal seal at the handbrake actuator. That's a BIG problem for two reasons. The rebuild kits sold by the usual vendors SUCK. They only have the rubber ring that seals the piston and the dust cover. They lack everything else. For example they don't have the rings that seal the two halfs of the caliper. Now I know the official line is don't separate the halfs but it's not really possible to clean it properly if you don't. Plus it seems to me that it's common sense to replace 20 year old rubber seals in the braking system while you have it apart.
Anyway...Does anyone know:
1. Is it possible to get to and replace the seal for the handbrake actuator on the brake caliper? It looks like it might be possible.
2. Where can I get that seal? For that matter, where can I get the seals for the two halfs, new bleeders, and the plastic nut style dust cover for the outboard adjuster. All stuff that should be in the rebuild kit.
3. Oh, and another thing. It looks to me like ATE used some sort of sticky non hardening goo to insure the inboard adjuster doesn't back off once it's set. Without this goo or something similar there is no way the handbrake could be expected to work for more then about 500 miles.
4. If it's not possible to fix a leak at the handbrake actuator then that means these calipers have a built in life limit of about 25 years so we will need to find a substitute. Does anybody have a caliper replacement that's inboard and has a working parking brake?
Thanks in advance,
Greg
