LiamGTR Posted February 18, 2012 Author Report Share Posted February 18, 2012 They do this during normal driving under NO braking How can they make noise surely nothing is touching them Link to comment Share on other sites More sharing options...
Steve74 Posted February 18, 2012 Report Share Posted February 18, 2012 i know it may sound daft , but have you checked the piston is working correctly on it... Have you checked the Handbrake shoes as they might have seized a little , cant remember if the celica has them or not been a while since i looked at that part.

rpsmith79 Posted February 18, 2012 Report Share Posted February 18, 2012 Have you jacked the car up and spun each wheel to see which one is causing the noise That way you should be able to pin point where the problem is coming from If it's the back end then it could be the hand brake shoes if they are internal to the discs like on the Gen 5 & 6 (not sure what the setup is on the 7) Link to comment Share on other sites More sharing options...

They do & it could be although if changed the discs surly would have adjusted the handbrake shoes ? Link to comment Share on other sites More sharing options...
GreyRacer Posted February 18, 2012 Report Share Posted February 18, 2012 If there is any run-out on the discs this can cause a rubbing sound against the pads especially with grooved discs. As Rich said, spin the wheel by hand. If the hand brake shoes were sticking this would show up hand spinning the wheels. If they are a little rusty just need to drive along in first gear with the hand brake pulled slightly on to clean them up. Link to comment Share on other sites More sharing options...

FlybyWyre Posted February 18, 2012 Report Share Posted February 18, 2012 (edited) Refurbed front calipers & P&P MTEC grooved discs & Red stuff pads ALL ROUND BRAND NEW rear calipers Full brake bleed twice All in the space of 2 months And my rear disc STILL makes a "Shh shh noise Why the FooK else can I do!? I'm skint! Help As stated, jack up the back of the car, spin the wheels and listen. If all the new parts are OK then I would suspect the disc shields have been distorted. You would see shiny wear if there is contact. Grooved discs can be noisy. I have MB AMG63 discs in the garage and to stop 2 tons from 200mph (de-restricted) there are no grooves. Next time buy standard discs, pads and change the brake fluid every 2 years. Edited February 18, 2012 by FlybyWyre Link to comment Share on other sites More sharing options...
LiamGTR Posted February 18, 2012 Author Report Share Posted February 18, 2012 I know it's the drivers side rear it I'll still get it up and spin thanks guys also David I'll do that hand brake thing anyway just to see if that'll cure it Link to comment Share on other sites More sharing options...
splinter Posted February 18, 2012 Report Share Posted February 18, 2012 (edited) Check for fouling on the shit shield behind the disk hub. Did you adjust the handbrake shoes by the castlated nut as your meant too?? I had scrapping when i changed mine, this is remmedied with a screwdriver held on the fouled area, then hammer to fuck till clear, sorted. Handbrake should be adjusted via this nut: - Wind it so its undone from clamping the wheel to allow it to move freely with the handbrake fully released, then pull your handbreak up to however many clicks up you want it, 3 or 4. Then you need to adjust the castlated nut so the pads are fully clamping your brake, ie, your handbrake is fully on. Try to match both sides to get an even handbrake setting come MOT time.

LiamGTR Posted February 18, 2012 Author Report Share Posted February 18, 2012 Did I adjust? I gave it all to my mechanic friend Splinter so can't really answer I've no idea I's have no idea about how to do or get into that position Link to comment Share on other sites More sharing options...
lta Posted February 18, 2012 Report Share Posted February 18, 2012 On my old 7 a stone had got into the hub of the rear disc and was trapped in the handbrake pads. Link to comment Share on other sites More sharing options...
LiamGTR Posted February 18, 2012 Author Report Share Posted February 18, 2012 I woulda thought he might have seen that today with the calipers off? I dont wanna big him too much so gonna take it to one of those 'free brake test' places Link to comment Share on other sites More sharing options...

I gave it all to my mechanic friend Splinter so can't really answer I've no idea I's have no idea about how to do or get into that position Hmm, print off my last post, hand it to your "mechanic" and tell him to sort it out. id bet a large wad of readies this is your exact problem. I woulda thought he might have seen that today with the calipers off? I dont wanna big him too much so gonna take it to one of those 'free brake test' places Dont do that, take it back to the guy that fitted them. get him to finnish the job!! He should of picked up on the fouling when testing before handing back to customers. the simple jack up and spin will tell you if its clear or not.

lta Posted February 18, 2012 Report Share Posted February 18, 2012 The handbrake shoes are inside the rear discs. That's why they have a deep hub on them, wouldn't be seen with the calipers off but would when the disc was off. Link to comment Share on other sites More sharing options...
bRinkz Posted February 19, 2012 Report Share Posted February 19, 2012 Splinter has probably hit the nail on the head for you here mate. I had exactly the same problem you had when i changed my rear disks a few months ago - couldn't work out what the hell was wrong, so took it all apart again and found there's two dirt shields on the rear. It's the little one that stops any crap getting inside where the handbrake shoes are that seems to disagree with any aftermarket disc - just needs a bit of adjusting. Easy fix and won't cost you a penny mate!!! Link to comment Share on other sites More sharing options...
lankyalien Posted February 19, 2012 Report Share Posted February 19, 2012 I would agree with the whole take it back scenario though I had a rubbing off side rear on my gen 6 and discovered the sliders where worn. Decent second hand calipers with carriers from Nix and all is sorted. thanx again Nix Link to comment Share on other sites More sharing options...
