Mathew2068 Posted February 8, 2017 Share Posted February 8, 2017 Left rear disc is getting a lot hotter than the the other three. Been into the garage and they've greased up the sliders, smashed my front bumper (other thread) and sent me on my way but it's still getting hot. Phoned another place and they want to replace the caliper straight away. Anyone have any luck moving the piston out just enough to give it a good clean and winding it back in again? Or should I just get a refurbished caliper? Tried to post on the wanted section but I'm not able to yet Any info be great, cheers! Quote Link to comment Share on other sites More sharing options...
Dnk Posted February 8, 2017 Share Posted February 8, 2017 (edited) Moving the piston out like that isn't a good idea, needs to come out all the way to be cleaned properly, it could be pitted and need replacing Refurbish the caliper, do the other rear at the same time, if it were me i'd be doing all of them Several places do this if you can't do it yourself and not crazy money, a mate got my front BMW E46 calipers refurbed for around £100 After the refurb change the brake fluid, bleed the system through unless you know its not that old Edited February 8, 2017 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
Scooter Posted February 8, 2017 Share Posted February 8, 2017 Firstly it's not a winding piston like some are. If you remove the wheel, then loosen one of the 14mm slider bolts and remove the other you can pivot the calliper away to give access to the piston. You could remove the piston side pad and put the calliper back in place and 'gently' (an assistant is better) press the brake pedal to push the piston out. Then if you have some big grips you can then pivot out the calliper again and try and push the piston back in. If you don't have grips you can make a wedge (block of wood) to fit between the piston and outer face of the calliper leaving just enough room for a spanner (something long to give leverage) to lever the piston back in. Rinse and repeating may free up the piston enough to stop/reduce the heat in the short term. Rear callipers can be removed and the piston pushed fully out by a bolt in through where the brake hose attaches and clamping in a vice, but we are entering the world of rubber seal replacing and refurbishing etc perhaps something you don't want to take on? Getting a good used/refurbished calliper is the sensible option if you aren't up for DIY. Quote Link to comment Share on other sites More sharing options...
Mathew2068 Posted February 8, 2017 Author Share Posted February 8, 2017 Ok cool thank you. I will have a look for somewhere that can refurb the calipers for me. Quote Link to comment Share on other sites More sharing options...
Mathew2068 Posted February 8, 2017 Author Share Posted February 8, 2017 I used to rebuild calipers when I rode motorbikes and had no kids...haha Time just seems to be hard to come by at the moment which is annoying as I quite enjoy the process. Just got to get the wallet out which takes less time! Quote Link to comment Share on other sites More sharing options...
Dnk Posted February 8, 2017 Share Posted February 8, 2017 (edited) If the piston is seizing its more often than not down to failing dirt seals letting in dirt/moisture, just pushing the pistons in and out may solve the problem short term but in the long term they will play up again, just refurb them properly and know you have good working brake system http://www.biggred.co.uk/ not used these myself but think others on here have and were happy with the results Edited February 8, 2017 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
SupraLEDrears Posted February 8, 2017 Share Posted February 8, 2017 Sort it straight away. My mate had the same issue and decided new wheels and painting the car was more imortant. The caliper snapped off of the hub and damaged his new wheel a few days later. Quote Link to comment Share on other sites More sharing options...
Scooter Posted February 8, 2017 Share Posted February 8, 2017 I think I've used this company back in the day, you get a refund on return of your unit, the cost is unlikely to be much more than a refurb on yours and it's a proper nice new shiny one!? https://brakeparts.co.uk/#!/shop/TOYOTA/SUPRA/93-01/SUPRA%20JZA80%20-%203.0%20NON%20TURBO%20IMPORT/Rear%20-%20Brake%20Calipers%20and%20Wheel%20cylinders/BCA2764 Big red are good too, I use their refurb kits now.

Mathew2068 Posted February 8, 2017 Author Share Posted February 8, 2017 Yeah soon as I noticed it I was getting it sorted. I've got to drive the car on sat to drop it in for bumper repair, that will be it till the refurbed caliper goes on though. I'll check out the links you guys have suggested. Thanks for the help.

Mathew2068 Posted February 8, 2017 Author Share Posted February 8, 2017 New caliper ordered from brake parts.co.uk, lets hope my old one is good enough to get my £30 refund! Quote Link to comment Share on other sites More sharing options...
Sheefa Posted February 8, 2017 Share Posted February 8, 2017 You could of refurbed it mate, but appreciate it does take time. Quote Link to comment Share on other sites More sharing options...
Samurai 20V Posted February 8, 2017 Share Posted February 8, 2017 Has the same issue a few weeks ago with one of the fronts on my car.. Got the offending piston out, cleaned it and refitted. Used the same seal as I could not get a new one in time. Working fine, was lucky not to damage the disc as the pad was almost worn out. Needless to say, got a refurb kit on order, gonna refurb all the calipers soon.. Quote Link to comment Share on other sites More sharing options...
shaky Posted February 8, 2017 Share Posted February 8, 2017 Anyone have a link to uk fronts refurbed ?, then i can just post my old ones back , thanks . Quote Link to comment Share on other sites More sharing options...
Mathew2068 Posted February 9, 2017 Author Share Posted February 9, 2017 I know, it pains me to spend money when I can fix things myself. Situations and lifestyle just force you to if you want to keep driving the car, which is why I bought it. Sadly I'm not planning on keeping the supra more than 6 months as another child on the way. It was my last chance to own my dream car while I could so I took it. So glad I did, what an amazing car! Sad too though as when I'm old enough for the free time these are going to be major money and hard to find parts for I love getting into my jet cockpit 3 times a week though, going to be hard to part with it.

brassbones Posted February 9, 2017 Share Posted February 9, 2017 (edited) I had the same problem a few weeks back and used these guys: http://www.ebay.co.uk/itm/TOYOTA-SUPRA-JZA80-NEARSIDE-REAR-CALIPER/122339243276?_trksid=p2047675.c100011.m1850&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20140107083358%26meid%3D7a1cd7b0c341449983edbccfee0aaf8f%26pid%3D100011%26rk%3D2%26rkt%3D10%26sd%3D381883233289 Fast on delivery and on processing my £30 refund. That said, Scooters link would appear to be cheaper if its also free delivery.

Mathew2068 Posted February 9, 2017 Author Share Posted February 9, 2017 Taking the car in tomorrow for fitting, waiting for the 'ooh yeah you need 2 new discs and a set of pads as well" The disc has no lip at all and the pads look pretty new. The disc hasn't been getting any hotter than a good fast road blast with lots of braking. Wheel isn't even getting hot really so I can't see it being warped, just that the disc is hotter than I know it should be. Should I get them to ring me when it's all stripped and have a look myself? Get them to show me the disc is warped (if apparently it is) I don't want to be paying for bits I don't need, waste of money and good serviceable parts!

Mathew2068 Posted February 9, 2017 Author Share Posted February 9, 2017 I've decided to keep hold of my old caliper and rebuild it with a kit (when I get a chance!). That way the next owner has the matching purple caliper to the others. Quote Link to comment Share on other sites More sharing options...
