Brake rebuild question
1969 corvette L46 with AC
I am in the process of rebuilding my brakes..
I am using lip seals in the pistons. If I eliminate the springs does this cause issues? Does anyone have experience with their brakes using lip seals without springs?
Thanks for your advice.

Tool
Years ago I bought a tool kit from one of the brake companies. It consisted of two stainless steel inserts, one for the back and one for the front. I would put the piston and seal in the insert and put the insert on the caliper bore and push the piston down into the caliper. I would use brake fluid as a lubricant. It is like using a ring compressor when building an engine. The kit also contained hard plastic pucks that were machined to fit the top seals, again, one for the front and a smaller one for the back. I would hit the puck with a hammer and that would seat the outer seal into the caliper. Doing it this way, you don't have to worry about nicking the inner lip with a screw driver or other tool. Jerry

I am rebuilding the brakes. Everything has go fine until it came to inserting the dust boots on the FRONT calipers. When I press the metal ring into the caliper--it pops right out. It's as if the ring is just a hair to small. The old ones were rusted when I took them out and now if I try the old ones they won't stay pressed in either. I repainted them put the new lip seals in, etc. The rear ones were fine but as I said the front metal ring will not stay in the bore. What gives????

I haven't done mine yet, but when I was reading up on how to do it, I came across this video. He puts the rings on at 15'...maybe it can help you

Those brakes are different. The stock c3 brakes don't have a split ring--the metal ring is fused to the dust boot. The dust boot must be pressed into the groove around the piston. Since no one is responding, I may try red high temp silicone to hold it is place--used on intake manifolds, oil pans, etc.--good to 650F. Brakes can get up 500F and in track use push 650F.

YES...I AGREE...the above video is useless when comparing it to a Corvette 4 piston caliper.
AND ...YES...I would make sure the groove or land is CLEAN so whatever you put in the to hold the metal ring on your dust boot will stick....as I knwo you know...but other people may not...so I thought I would write it.
Seems like your choice in product to hold your dust boots in place may be the trick.
