Dust seal
Beware when you remove the piston with a compressor, even 20lbs of pressure will crush youre finger if they get in the way.
Put something beween the caliper arms(wood) to stop the piston coming right out suddenly.
The dust seal can usualy be replaced without taking the piston out completely, use brake fluid to lubricate it.

Adapt a grease gun to fit or use an air compressor. Replace oil seal while its out.
I purchased my kits from Totton Motor Factors 023 80863631. Cost about £20 for Dust covers and oil seals. Possible cheaper else where.
When refitting a little bit of patience and a vice will make the job easier. Take note on johnmors point of safety.

Getting the dust seals back in tends to be tricky, nigh impossible wit the the caliper bolted together.
I split the calipers (watch you do not lose the small 'o' ring) then use a big socket as a drift to get the dust seal in squarely. You
will only get one attempt at this. If you have a piller drill you can use this as a press.

Don't put a gease gun or air compressor near it --- the former even the slightet trace of mineral oil ruins seals and and the latter because
compressed air is dangerous too much stored energy.
Pump te piston out using the brake pedal then clamp the pipe.

i used an airline at work to 'pop' the pistons out very carefully,then split the calipers to inspect/change the seals

Also you don't need to split the caliper.

This is very dangerous --- because air is compressable compressed air is stored energy. Always use hydraulic pressure.

Hi there
I used a compressor for mine, along with a piece of wood as previously suggested.
I got brake seals and new pistons from:

They were vert helpful and a good price!
Cheers

thanks alot some great ideas il try a foot pump first. im still building the car and to get the brake lines and pedals in will take ages. I think
taking heed of saftey side of it will be a good idea for me. The pic is in october not much has changed since then

Beware of splitting M16 calipers. there are issues with reuse of the bolts, and the difficulty of sourcing replacement bolts that was enough to make
me decide to trade mine in for professionaly rebuilt ones. all discussed in the archives.
