One of my front calipers, front near side, has started sticking slightly. A forum member on here had a pair of calipers for sale for £60 that required a refurb. I have contacted BigRed and they want £140 to refurb both of the calipers to a 'as new' condition. So, for £200, I am getting two as new calipers. I have never used BigRed before but so far have been happy with there response times. I emailed for a quote and got a reply within the hour giving me a full quote. I will update this thread with photos before and after next week when I get the calipers back. I dont think £200 for two as new front calipers is too bad. Brakes International have them listed for exchange for £65 excluding VAT and delivery - however are out of stock. I also worry on exchange that you will recieve a non genuine, non M stamped caliper in exchange for your genuine one. Doing it this way, I have my old genuine M calipers after to either sell back on as used, refurbish in my own time, or get bigred to also refurb those for me to sell on. I will keep you updated and give a review of the service I receive from BigRed.
