About this deal

Although the mechanic said it was letting dirt in I can't see any full splits in it, however that is only visual inspection and I am aware that it could be split and I'm not just seeing it. If there is damage when I take them apart I'll replace them. With piston still protruding fit the dust seal, a little red grease helps push it in the recess. Once in secure with the metal ring, easiest to keep the open end of the ring away from the bridge of the caliper. This often the hardest part as you need to push the ring into the recess, which is allows a fight as you try not to puncture the dust seal. Once seated pull the dust cover out so the outer end fits into the recess on the piston. Move the piston in and out to ensure the dust cover stays in place. Once seal and piston are fitted and ready to be rewound fully into the caliper, either use a proper tool or improvise with wide pipe grips to grip the very end of the piston and rotate bit by bit to screw it in. With mating/sliding parts lightly lubricated with fresh brake fluid, insert the fluid seal in the caliper, slide the dust seal over the piston, offer the piston/seal to the caliper and work the piston around like stirring a bowl to help the dust seal pop into place. Wind the piston in, remove the arm for the handbrake from the rear of the caliper. With a rubber hammer or a piece of wood tap the bolt the handbrake mechanism into the caliper. This will push the piston out a bit, then using air blow the piston out. A foot pump will do if you don’t have a compressor. Use the plastic tapered connector that comes with pumps and apply it to the brake pipe inlet after you’ve removed all the brake fluid. Otherwise use some grips to remove the piston. I wouldn’t recommend reusing the pistons as replacements are cheap enough. The piston will come out with the handbrake mechanism attached and it simply screwed off from there.

I think I am getting myself mixed up, you are correct there is no need to remove it, I was remembering when I had to change something else which required it's full removal! Edit. This is all from memory but it should cover it all. Don’t forget to clean up the pad carrier and lightly grease the slider pins. Depending on the depth/amount of any corrosion you may be able to clean it up with some very fine sandpaper. Obviously this will only be a temporary repair but it will last a while - monitor for fluid loss. Thank you, I thought it was a M14! I'll buy one tonight, they will have to come off to get at the seals properly! Having read what the others have said it would seem these ones wind out! Thank you to everyone else also, this has given me far more confidence to do the work and what tools are needed!
