there may be trouble ahead...

so decided to strip the brakes down. they were in a shocking state (suprise suprise) took the pistons and the seals out of the front caliper and split the rear caliper. the seals look fine and i was very careful removing them so i'm gonna use them again. The pistons were quite scabby so i'm gonna emery cloth and polish those and refit. not intending to leave it this way mainly to familiarise myself doing a stripdown. next was cleaning the the rear caliper... :eek pistons are jammed in hard you can see the dust seal sticking out in places also. there was a huge amount of mineral deposits in and on the caliper. made good progress with a big bucket of hot soapy water and a toothbrush but the hard stuff would not budge. Attacked it with a very small electrical screwdriver and chipped and scraped the worst of it off. What remained was easily dissolved with a thick toilet cleaner that has limescale remover. pour it on watch it fizz came out pretty nice. air won't push out the pistons so im gonna rebuild the rear and see if i can force them out using the hydraulic pressure... wish me luck
