Advice on wheel squeak please

[joesmad4it]

Dunno if it's been happening for a while or it's a recent thing but noticed a high pitch squeak coming from what I think is the drivers front wheel. It's not felt through the steering wheel so don't think it's bearings, me old man reckons maybe some grit in the callipers but I'm not so sure. Any suggestions appreciated

 

[Slimy]

I don't think it could be grit, that tends to get kicked out as quick as it arrives. My money is on a corroded/bent disc shield, the thin piece of tin that sits just behind the disc and pretty much just gets in the way. It's only thin so it tends not to do any damage, but for the same reason it can get bent and rest on the disc.

Get the wheel off, put your hands round and check that the only thing touching the disc is the pads.

Bearings dont squeak they rumble and grind then they go bang! High pitched squeaks/squeals are generally brake associated, if its constant then it could be either a sticky piston in the calliper, something jammed in the calliper or worn pads, if it goes on and off as the wheel turns its a warped disc.

I had new pads put on old discs and they squealed, even at 60mph!

It turned out that the pads were rubbing on the lip that was worn from the old pads.

Worth checking that nothing is caught between the disc and the disc guard as well

Thats kinda what it does but it's intermittent. Braking can sometimes feel like it's kangarooing if that makes sense would that confirm this as I thought the cupra discs very rarely warp?!

It's not really during braking, in fact firm braking stops it momentarily. Will whip the wheel off I think and have a look.

I wasn't braking when they were squeaking. Even at motorway speeds it was still there (without braking). Firm braking also stopped the noise for me

I have the same intermittent squeak and it's driving me nuts stops when braking though

Check wheel nut torque and/or put some copper grease on the hub where the wheel goes on.

Tanks guys, I'll try all the above and let you know.

Am I right about it being very rare that the discs should warp?

I am have in intermittent squeak when i turn left! any ideas? cv joint may?

 

[Cal91]

I have this too! I had it with my last Ibiza also.

When the wheel is slightly turned it has a intermittent squeak, you can only hear it with the windows down.

I just put it down to my heavy braking :\

 

[rod the sod]

i think that my problem is low brake pads!!

 

[joesmad4it]

So I decided to change brake fluid and sort this squeak out once and for all so first got gunsons easy bleed kit and it was amazing, changed fluid in 20mins. While I had the wheels off I decided to take off the calipers (easier said than done thanks to those bloody pins) and copper grease the pads. On closer look the pads were terribly low so shopped around local places for some but gave up and put the old ones back on greased till I get some more.

The squeek just got worse so now own a nice set of Ferodo ds2500's which will go on at the weekend. My question however (eventually) is why do the AP pads have a tapered top to them and the Ferodos don't?

 

[darkhorse]

Pads are usually tapered to reduce the likelihood of braking noise ie squealing. You can taper them yourself if you think it needs to be done.

I found the DS2500 pads to squeal a tiny bit when braking very lightly but eventually the noise went. I think it was because of the combination of the pads and grooved discs (ATE Powerdiscs) but it was so quiet it never bothered me anyway.

I've got Brembo Max discs to go on mine soon and I'm debating whether to get DS2500 pads again or just use std Mintex which are £75 cheaper!

I'm gonna put them on and see how it goes but the squeal can't be as bad as it is now. I'm gonna keep the discs as they look in rather good condition, will upgrade when I do the rears (advice appreciated if not)

£75 cheaper? Mine were only £100 plus p&p, how much are Mintex pads?

 

[rod the sod]

Hey, just to let you kno that i have the ap racing pads and pin kit for £70 off the dealers, i dont kno if thts a good price or not - i thought it was tho! i am changing mine shortly!

Oddly enough the Mintex pads are £25

Mintex 2041 pads are £25 -£30 on ebay and are excellent! On my TT 312`s anyway.
