bigbloodyturbo Posted May 11, 2009 Share Posted May 11, 2009 Should there be any play in the rear pad carrier? I'm on jspec rears and after trying to chase up a knocking sound I have, I found some play between the carrier and the caliper, its not much but when you push and pull on it you can hear a slight knock as the carrier moves.

pistonbroke Posted May 11, 2009 Share Posted May 11, 2009 Does it do it when the handbrake is on? Quote Link to comment Share on other sites More sharing options...
bigbloodyturbo Posted May 11, 2009 Author Share Posted May 11, 2009 Does it do it when the handbrake is on? No the rattle goes away when the handbrake or the footbrake is applied. Quote Link to comment Share on other sites More sharing options...
bigbloodyturbo Posted May 11, 2009 Author Share Posted May 11, 2009 Does it do it when the handbrake is on? I think I had a blonde moment, yes the carrier still moves when the handbrake is on. Quote Link to comment Share on other sites More sharing options...
adnanshah247 Posted May 11, 2009 Share Posted May 11, 2009 bud im pretty sure you had the same issue as me, every time you hit a lil bump you would get a knock because the pad is moving around. Quote Link to comment Share on other sites More sharing options...
pistonbroke Posted May 11, 2009 Share Posted May 11, 2009 I don't think you should be able to move it when the handbrake is on, the caliper should be forced to grip the disc and it should be solid. If it's not, I say the caliper is sticking. Quote Link to comment Share on other sites More sharing options...
adnanshah247 Posted May 11, 2009 Share Posted May 11, 2009 isnt the hand brake mechanism on the inner side of the disk with shoes? the pads on the outside should move because the handbrake doesnt push them the foot brake does. Quote Link to comment Share on other sites More sharing options...
bigbloodyturbo Posted May 11, 2009 Author Share Posted May 11, 2009 I just opened the caliper up and both rattle springs are in there. The pads have plenty of life left and all I can see is this movement between the caliper and carrier. I just ordered some slider pins from toyota so I should get them by wednesday. Hopefully that should take up some of the slack. @Adnanshah: How did you stop the your pads from rattling? Quote Link to comment Share on other sites More sharing options...
adnanshah247 Posted May 11, 2009 Share Posted May 11, 2009 got the metal tension pins that hole them in place. no more movment = no more noise. Quote Link to comment Share on other sites More sharing options...
bigbloodyturbo Posted May 11, 2009 Author Share Posted May 11, 2009 got the metal tension pins that hole them in place. no more movment = no more noise. Both my spring pins are still in place on the pads so it shouldn't be that. I see i'm going to have fun with this problem:( Quote Link to comment Share on other sites More sharing options...
adnanshah247 Posted May 11, 2009 Share Posted May 11, 2009 ahhhhh you see, thats what u thought, the pins on the pads do squat all!!! thats what i thought until i saw on the other side there are actually metal clips inside the actual calliper that hold them (the pads) in place, the ones on the pads are just added on!

My bad, I was thinking of my old s2000 mechanism Quote Link to comment Share on other sites More sharing options...

If you mean the plate pad supports, they're there aswell, nothing missing as far as I can see. Quote Link to comment Share on other sites More sharing options...
DodgyRog Posted May 11, 2009 Share Posted May 11, 2009 The picture bottom left shows all the clips and bits you should have around the pads Quote Link to comment Share on other sites More sharing options...
bigbloodyturbo Posted May 11, 2009 Author Share Posted May 11, 2009 I have everything on the bottom left picture except the anti-squeal shims, but they wouldn't cause this rattling. Quote Link to comment Share on other sites More sharing options...

If you don't have the anti-squeal shims, do you have the clips that go on the sides, as these hold on the anti-squeal shims, but also fill the gap down the side of the pads and caliper. My fronts use to knock on breaking and this was due to the pad moving because I didn't have the side clips. To be sure I would get a full shim kit and replace all the springs and clips etc. Do a search for Steve Manley (Toyota Oxford I think), he is fairly quick and usually very cheap compared to your local Mr.T Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted May 11, 2009 Share Posted May 11, 2009 The holes in the calipers the pins go into will be worn. If it bugs you that much new calipers will sort it. It MAY be possible to have them bored oversize and phosphor bronze liners inserted, but unless you know a machinist who owes you a BIG favour it could well cost more than new, or good used calipers.

Cheers Chris, I'm going to try a used jspec caliper and its booked in to go on a ramp later this week just incase its a driveshaft centre bearing or cv/uv joint, I'm praying for it to be a shagged caliper after talking to Mr.T today about replacement prop shafts.

bigbloodyturbo Posted May 12, 2009 Author Share Posted May 12, 2009 Ok, this is my second blond moment in as many days but I found the source of my knocking noise. The noise was coming from the rear nearside and so I concentrated all my efforts there. I had the wheel on and off loads of times and jacked up. It wasn't untill someone (Heckler thankyou) mentioned checking the wheel nuts. The nuts on the nearside were fine but I thought I'd best check the other side, it turns out one stud had sheared off completely and the one next to it had just lost its nut. Needless to say I feel a proper knob asking all these questions with it being something so obvious but atleast I caught it before the rest let go:blink: Quote Link to comment Share on other sites More sharing options...
