Samsar Posted December 4, 2014 Share Posted December 4, 2014 Morning all, I use my car as daily and on the way home from work last night the car didn't seem right. Something made me think I had a puncture on the N/S/F. I got out and had a look and all was fine so I checked the disc and my god it was hot and I mean really hot. I checked the O/S/F and that was warm but nothing like the other side. My question is what would cause this? I've already got some new discs and pads in my garage ready to go on the front but could it be something else causing that disc to get redders?

Samsar Posted December 4, 2014 Author Share Posted December 4, 2014 Sticking calliper. Cheers mate. Do you think when I change the discs and pads it will free it up or is the caliper knackered? Quote Link to comment Share on other sites More sharing options...
Graham1984 Posted December 4, 2014 Share Posted December 4, 2014 When my callipers were sticking I had them freed up and they started again. Iirc you either need to refurb them or replace as if they stick on your new set the heat generated will just knacker the new set, of pads and discs faster. When my caliper was sticking I also got juddering and noise at around 90(ish) on a private track. Before you take my word as being right for the love of god wait for someone else more knowledgeable to come along first and give their input Quote Link to comment Share on other sites More sharing options...

Dnk Posted December 4, 2014 Share Posted December 4, 2014 (edited) Refurb properly or buy new, freeing them off is a waste of time as they will sooner or later seize up again What calipers do you have, 2 piston j specs or 4 piston UK spec ? It would pay you to have a close look at all four calipers, at the minimum get them refurbed by Big Red or similar brake refurb specialist. At the very least do both fronts !! Also check the brake lines and when you do the calipers it would pay to replace the brake fluid in the whole system at the same time, easy enough to do and brake fluid is pretty cheap, you'd only need 1-2 litres max Edited December 4, 2014 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
Samsar Posted December 4, 2014 Author Share Posted December 4, 2014 What calipers do you have, 2 piston j specs or 4 piston UK spec I've got the j spec ones. How dangerous is it to carry on driving? My work is about 6 miles away and use it to get there. Quote Link to comment Share on other sites More sharing options...
Dnk Posted December 4, 2014 Share Posted December 4, 2014 (edited) Very in my opinion, needs fixing asap like yesterday It could be the carrier seizing on the sliding pins if its a j spec caliper, or it could be the piston/s also seizing get it looked at if you don't know what to do, pretty simple for any decent mechanic to deal with. Not worth doing it yourself in my opinion unless you know what your doing and have the tools to do the job properly, for what the refurb comps do it for i wouldn't mess around with them Have a search on here as a few members have used the refurb comps and were very happy with the job done etc http://www.biggred.co.uk Edited December 4, 2014 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...

Graham1984 Posted December 4, 2014 Share Posted December 4, 2014 I got a set from Parry 2nd hand for about £50-60 delivered, Tcb parts were around £80 plus vat and delivery iirc (per one) and as for refurb kits I'm not sure about the price, plus you have to factor in paying someone to do it. Hope that helps. Quote Link to comment Share on other sites More sharing options...
Graham1984 Posted December 4, 2014 Share Posted December 4, 2014 Just a quick point though, remember 2nd hand units run the same risk of seizing up as well as your current set. I took the gamble and it's been fine so far (fingers crossed) Quote Link to comment Share on other sites More sharing options...

Cheers for your help guys If your useless with mechanics then yes get someone who knows what their doing to check them out for you, it would make sense to do all four as they will all be in a very similar condition.

Dan_Turism0 Posted December 4, 2014 Share Posted December 4, 2014 if you have Jspec's chances are it's the sliders that are sticking not the piston, it's a common issue and a cheap fix had it on my supra and IS200 which use pretty much the same calipers. I've refurbed mine and also done a friends too Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 4, 2014 Share Posted December 4, 2014 Either could be the cause, you can free sticking slider pins and re grease using high temperature molybdenum based grease. A sticking piston(s) in the caliper mean it needs a strip and rebuild, not for the feint hearted. I supply stainless steel pistons and also seal kits if you decide and once and for all fix of your existing calipers. If the caliper piston(s) are seized it's almost certain the chrome on the pistons has broken down and just cleaning and re using them will just be a short term fix.

Samsar Posted December 4, 2014 Author Share Posted December 4, 2014 I took the wheel off and had a look to see what's what. I rang Keron to see if he had any refurbed calipers in stock and he also said it might just be the slider pins. Had another look and decided I didn't have a clue so put the wheel back on and parked it up My dad came over and we chatted about s**t and then my neighbour came home from work and we started talking a bout his Porsche he's got locked in his garage. Oh well tomorrow is another day and I'll get it looked at by someone that knows what they're looking at Quote Link to comment Share on other sites More sharing options...

Maybe you could get it/them freed up, but if I was you I would be sourcing some more afterwards quite quickly. Quote Link to comment Share on other sites More sharing options...

Hi buddy, nope still in Kent (Trashford). I'm going to see if I can get someone to come around tomorrow and have a gander at them and see what's what. If I get no joy your offer of coming down would be much appreciated. Can I let you know tomorrow how I get on and we'll go from there?

Benjy Posted December 5, 2014 Share Posted December 5, 2014 Just pop the wheel off and then undo the bottom bolt on the brake caliper. Flip the caliper up and see if the bit you just flipped up slides in and out freely on it's pivot. Then grab hold of the bottom slider (that the bolt you've just removed screws into - will have a flexible rubber sleeve covering it...) and see if that pushes in and out easily. If both sliders move, it's the caliper. Quote Link to comment Share on other sites More sharing options...
Dnk Posted December 5, 2014 Share Posted December 5, 2014 (edited) In a nutshell your brakes are 20 yrs old, it's time too overhaul them rather than pissing around doing bits on them.
