jimsup Posted March 27, 2011 Share Posted March 27, 2011 Hi guys, One of my rear brake callipers have siezed it looks as my brake disc is staying rusty after a drive so looks like i am going to need a new one though might as well replace the set incase the other one does the same? is it a case of a new set or is this a common problem which can be resolved with WD-40 and rubber mallet lol Any ideas? or does anyone have a set? and possible cost?

Jim You could buy new, but you would most likely need all 4 as 2 mint rears and 2 rough fronts wouldn't be a good combination. It would also be expensive and not really cost effective as 2nd hand they aren't worth a lot. Another option would be upgrading to UKs all round. There are a few pitfalls here also, if you buy new it's very expensive (around £1k), if you buy 2nd hand then you might be back to the same situation in no time. It would be a little bit of a gamble really. The best option IMO would be to get both sets of calipers refurbished with new seals and pins/pistons as required. This will have the calipers working as new for a fraction of the cost. Will take a bit of elbow grease to do the refurb but it is a fairly straight forward task. If you pay to have it done it might not be quite so cost effective. HTH Quote Link to comment Share on other sites More sharing options...

bluecoup Posted March 27, 2011 Share Posted March 27, 2011 service kit is about £35, pretty easy to do, but don't play with brakes if your not sure what your doing, some wd40 under the piston boot and pushing it out and in a few times might free it off, but it will come back and is not a long time cure, Quote Link to comment Share on other sites More sharing options...
jimsup Posted March 28, 2011 Author Share Posted March 28, 2011 cheers for all your help guys, probably a 'stupid question alert' but why would replacing both rear calipers would it feel twitchy under heavey braking? Quote Link to comment Share on other sites More sharing options...
Scott Posted March 28, 2011 Share Posted March 28, 2011 cheers for all your help guys, probably a 'stupid question alert' but why would replacing both rear calipers would it feel twitchy under heavey braking? Because the rear calipers would be performing at their optimum, the front calipers would be worn an unknown amount. If the rears performance outweighs the front then your car will quite quickly change ends. Have a read at the brake threads that have popped up in the last hour and you will get some info Quote Link to comment Share on other sites More sharing options...
scotty71 Posted March 28, 2011 Share Posted March 28, 2011 What about people who change to UK fronts but leave the J Spec rears? What would this do to the break bias as from what I have seen of Uk's I nearly hit my head on the windscreen - Im on J craps Just curious Quote Link to comment Share on other sites More sharing options...
