Braking question

[Guest Boxhead]

Ok,

before you jump in saying use the search function, i would like to let you know i have and didnt find anything exactly what i was after..

When i brake i find that my front brakes squeek, sorta on and off, sometimes on, now i know the pads are not fully run down...

however, my first question is, if these werent replaced at compliance, is it possible for the pads to become stale after a while if they have been on the car for a while without much use?

and secondly, i have slotted stock rotors, and was thinking about getting them machined to fix this problem, as it annoys me... but i dont want to go in spending money if i dont have to.. as in if i do machine them and it doesnt fix i wont be happy

comments appreciated

Boxhead, my stock discs have been slotted and i get squeaking only in reverse. could you swap pads with somebody for a day and see if they make a difference?

Hi Michael,

I had a squeaking problem that sounds a little bit like yours on my WRX which if I'm not mistaken has a very similar brake setup to your GTS-T. Mine would squeak at random times but not when I applied them. I had just fitted new pads (Bendix Ultimates) which were slightly larger than the OEM pads and the lip around the edge of my moderately worn rotors had worn a groove on the outer edge of the new pads. I took the rotors off and got the lip machined off for about $25 and the squeal was gone.

If this sounds like what's happening to you and you have got a distinct lip around the outer edge of your rotor then machining them could be the way to go.

Hope this helps,

Ben

do the pads have those anti squeal plates on?

Im not sure that you can machine a slotted rotor :confused:

Do you know what brand of pads they are?

I'm pretty sure there's no dramas machining a slotted rotor Duncan, but someone please correct me if I'm wrong. I'm now using Bradi slotted rotors which will probably get to the wear limit or crack before I need to machine them.

Not sure about slotted/cross drilled though. Wouldn't touch them with a 10 ft stick.

no im not sure of the pads...

so far on all of my cars i have totally eliminated all squeeling by using the "stop squeel" compound. Its available from most automotive stores, is fluroescent orange, and comes in a bottle of maybe 200 or 300 mLs (there abouts). Its like a high temp silicon compound and you put it between the back of the pad and the antisqueel shim or brake caliper, and hush, it's all gone. It's fixed 3 out of 3 for me so far so could be a cheap fix for you.

Your pads could just be glazed. Do a search in a thread started by DBA steve a while ago called "Disc Rotors". The fix was something like pulling your pads out and giving them a light sand back with emery paper. Check out the thread for more detailed (and more importantly) accurate info

yer im havin the same problem Michael, i just changed my front ones to bendix, got nfi how to get it to stop though. i got my stuff machined and stuff, still screwed though

could be the overlap issue, i had that on the 31. Try the anti-squeal stuff locutus recommended, and while the pads are out, sand them back. If that doesnt fix it at least youve eliminated all those options.

Prank- I get a squeek in reverse only (cept for when they are cold, which is when they squeek all the time) as well. Does anyone know why brakes would squeek only in reverse?
