Hi all, Just after some general info on doing up my rear calipers. Iv'e bought two kits (just with O-ring and rubbers etc.) Is De-Greaser OK to soak and clean every thing up when ive stripped them or do i just use metho. Iv'e heard not to use petrol!,Also 800-1200 Wet and dry to clean up bore and piston? When putting back together Rubber Grease?, Just Brake Fluid? Cheers for any help.
Degreaser is OK for cleaning, but wash the bits thoroughly with water afterwards, and dry completely.
800 W&D should be OK, but just use light even pressure. 1200 is OK too, but will take forever to do anything.
Rubber grease for reassembly.

Cheers Tony,I was hoping de-greaser would be OK as it cleans up real well with a good soak, I have a compressor so will use air inbetween cleans.It sounds silly but should i wet and dry the bore in a round motion and not in and out.lol.The dust seals and fluid in the lines on the diff i got was clean and boots intact so i hope no pitting/rust.If i get them back together and put fluid in through the bleed hole,and replace nipples they should be OK sitting around for a while? Well a month or so till diff goes in.? Cheers
It's not a silly question. Sand the bore in a round motion.
Before you put the callipers back on the diff, use compressed air to blow out the brake pipes and hoses. Have a close look at the brake hoses, it could be a good time to invest in some new hoses.
Your callipers will be OK sitting for a while as you describe.

Cheers ,will do,the hoses do have small cracking on them (the rubber ones). So i will take every thing of and give the whole diff etc. a good clean and even paint it! And replace rubber lines. I know i wont notice alot of difference from drum to disk but one of the axle seals has been leaking for years (slowly) and my right shoes are soaked! So with the new disk one in should be good!!!
Psssst Boys if I may suggest... you can buy brake cleaner in pressure pack cans. Also good for this application.
Bl**dy hell i got a can of that!!But after 3 right second hand calipers i got them done! Pistons slipped in by hand and all the sliders greased up,new dust boots etc. Just gotta swap diffs!!!! Shoped around for new rotors Protex half the price of others $120 for both, Got the same on the front (Protex) and had no drama's with them.Quote:

The guys at BGT brakes in Dandenong Victoria were very helpful for supplying pistons for my twin piston fronts. No one else seemed to know or care.
I used to work in a brake shop and this is how we did it.
soak callipers in hydrochloric acid for an hour then use wire brush attachment on small air grinder to clean the calliper and piston. if there was any pitting or grooves in the piston or calliper they were binned. then just a matter of rubber greasing the piston, calliper and seals and put it back together then bleed them. most of the time we would paint them silver to make them look flash.
