    OK, I got the brake lever off - with some difficulty. Now, I can not get the springs out of the caliper body. This vehicle was often submerged in 1-2 feet of water for a few years. There is MAJOR rust buildup. Would I be better off using a propane torch to heat the area so expand the metal on the caliper or should I just take my time with the WD40 and slowly work it out.

    Thanks

    Normally when rebuilding calipers I put the air blow gun (rubber tip) where the banjo bolt goes in and blow it out. Put a block of wood where the rotor would go, or a thick wad of shop rags. Be carefull, it is very easy to smash your fingers or shoot the piston across the garage. You may wish to turn down the regulator on the air supply. If you don't have a compressor, you can rig something up to use an aired-up tire instead (also works good for blowing the dust boot around the piston if it pops out on reassembly).

    However, if they are really that rusty, there's a good chance the pistons are hosed, especially if the calipers had water IN them. The pistons are really expensive, and if they are hosed you'd prolly be better off using your calipers as cores on some remans.

    Better Explaination:

    I am talking about the eBrake return lever spring - The external spring that provides tension to the Ebrake return lever. The part of the spring that attaches to the caliper itself is rusted in. I am wondering the best method to extract this spring without destroying it - I REALLY NEED IT!

    Ahh, I see. In that case, I'd try plenty of WD and maybe a LITTLE heat. Why do you need it out?

    I need the spring to use on the remaufactured caliper I bought. The reman calipers do not come with the ebrake lever or return spring.....so.....I need to get this one off!
