I decided to have a got at the Caliper refurbishment myself having removed the front and the rear calipers from the IRS as several companies quoted costs in excess of £800. Whereas for less than £120 for “electro cleaning” it was an easy decision having acquired new seals, pistons and other required odds and sods from SNG Barratt for less than £200.
Rust removal on the calipers was hardwork compounded by the need to get into the fiddly nooks and crannies. This was achieved by using a Dremel (or Craftsman in my case) and finally, ensure that you use a mask and safety glasses.
Finally, the calipers have now been resprayed with a specialist Brake Caliper Paint Kit, supplied by Brake Caliper Specialists based in Long Eaton, Nottingham. This paint is allegedly better than anything else that you can buy on the market and talking to fellow builders, it comes highly recommended and whilst not perfect I am really pleased with the outcome.
