Thank you to everyone else also, this has given me far more confidence to do the work and what tools are needed! Also with the rears am I correct in thinking I need a special tool to remove one bolt? M14 spline bit is what I vaguely recall needing?!

On my last service the mechanic noted that the rubber gasket around the piston on both rear callipers was worn and letting dirt in. I’ve bought 2 rebuild kits for the rears however I was just looking for clarification on how the pistons come out. I know on the fronts I can use compressed air to blow them out as I have done that before, however with the rears I’m unsure if they need winding out or blowing out… or some total other method. Hope this makes sense. 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. 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! The Laser 7 piece Ribe Bit Set are specifically designed for use on cylinder head bolts and suitable for use on Alfa Romeo, Fiat, Lancia, Saab & Volkswagen cars.

The new seals are an absolute pain to put in, the piston will need to be cleaned also but as mentioned above they will be scored or even pitted. Will get you by a few thousand but not a permanent solution. Buy new when can. BRISKODA is owned and operated by Summit 360 Ltd, registered in England & Wales, company number 05710517. 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. 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!

I know this is an old thread, but the post by CWARD is of interest to me. I'm currently restoring an old caliper off my Octy PD 1.9Tdi Estate and I cannot figure out how to remove the handbrake spindle. Everything else is off but I need to get the spindle out as it's damaged from being seized. Is it possible to get this spindle out, or is it new caliper time? The views expressed herein are those of the individual contributors and not necessarily those of BRISKODA or SKODA.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.

Apologies, I forgot to mention that there is an internal circlip holding the handbrake mechanism in the calliper, remove it and it should come apart easily... Alzheimer's!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. 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.

Obviously this will only be a temporary repair but it will last a while - monitor for fluid loss.The Halfords Advanced 11 Piece Spline Bit Set offers a winning combination of strength and precision. The steel shaft sits in a brass bush which is fitted to the alloy calliper, I wouldn't imagine the bush is available as a spare part.
