Unfortunately my brakes stopped working all together a few days ago, on removing the front brake drum it was full of brake fluid.

I have removed the faulty/leaking brake cylinder however I am unsure how to remove the piston and fit new seals.

Any help would be much appreciated,

Thanks,
Rhys.

Get a new one! Should only cost between about £10-£20. Youll probably need new shoes too ifs covered in fluid.

You can reconnect the cylinder to the car without the shoes, use a large grip to check the other cylinder, and then press on the brakes; or use an air bed adapter in a foot pump and blow the piston out (watch where it's pointing. Although seals are very cheap, a new cylinder is not expensive and might be a better option. When fitting new shoes, remember to fit to both sides of the car at the same time.

The advice to get a new cylinder is very good! But in extremis - if you really want to keep the old one and the piston won't come out any other way (and usually they just fall out if they have been leaking) - then I found my grease gun has a screw fitting which is the same as the cylinder thread - and stuck pistons can be expelled by pumping grease in! Of course - they must then be thoroughly cleaned, any rust marks removed with fine wet/dry - and new seals installed with a smear of special red brake grease. You may as well change both cylinders (or both cylinder seals) while in there - and new shoes are an absolute MUST! Old shoes that have been soaked in fluid cannot be re-used.

as bmc says they can be got out but to be honest the time spend stripping and cleaning is probably longer than fitting new units and not as safe,what price safety
