front calipers for 82 308

my 79 uses the same caliper (ATE) as a Porsche 911. I cracked one of mine and spent 100.00 on a used 911 caliper.

 

Sounds like that person cracked them trying to get them apart.
and yes they would have leaked if they were cracked originally.

 

I have never heard of the brake calipers cracking. The rubber seals and dust boots will crack with age, but the caliper bodies are very robust, and would take a huge amount of force to cause them to crack. Where did they crack?

 

True.

 

They may have cracked the bolts that hold the 2 halves together in trying to separate the 2 halves, but if your mechanic is a butcher anything's possible and they could have cracked the housings
Rebuild parts and calipers are available from Superformance in the UK, the ATE caliper was also used on many early 70's Alfa's but the Ferrari uses a spacer between the caliper halves as the Ferrari uses a thicker disk rotor.

Gentleman, to clarify, This car has sat for a while, and the front calipers were frozen, and rusted. The only way to remove the pistons out of the caliper castings is to pressurize the calipers, first with compressed air to have the pistons move outward. If that doesn't work, gentle heat is applied to thermally expand the castings, and more air pressure is applied. If that doesn't work, then the caliper is filled with fluid, and then a pump is attached to the caliper, and hydraulically the pressure is increased to a point where the piston will move. In this case, the left side pistons moved successfully with hydraulic pressure, with no adverse affects, but the right side caliper housing cracked with the pressure applied. It's unfortunate, but I know of no other way to dismantle the calipers. The only other option was to not try to save the calipers, but just automatically tell the customer he needs two replacement calipers. By attempting to dismantle and rebuild, monies were saved.

Gary,

Might touch base with jim400i here.....he has come across some brake/suspension items recently.

I know as I bought some spare front/rear brake rotors, to hang on the garage wall until I needed them!

It seemed to me he had calipers and 308 suspension bits at that time.

You could always drill into the pistons and slide hammer them out!
Sounds like some heavy moisture in 'da fluid there......

 

They were Ate's answer to the 3 stooges, Musty, Rusty and Crusty!
