Squeaky brakes

[aesc]

Hi,

Ive noticed on my Levin that im getting a squeak from the right front disc when pushing in the brake pedal.

What could be causing this? Should I be getting this attended to?

Thanks

Usually brake pads getting worn down, had that on my BMW when I imported it, got machined rotors and new pads, all fixed.

Pay to get it fixed pretty soon. A lot of pads have a little indicator on them (little metal tag poking out) that starts to run on the rotor when you've got a couple of mm pads left. Thats probably the noise you've got. If you leave it too long the tag starts to make a groove in the rotor and you might need a new pair (not really something you want to pay for).

Could also just be a stone in the brakes somewhere.



If you want to change the pads yourself its pretty easy. Whip the wheel off, remove the bottom bolt on the brakes and it should lever up and the pads will basically fall out. Push the piston back slowly with something (making sure the brake fluid reservoir doesn't overflow), throw new pads back in, put that bolt back on and wheel on.

Pump brakes a few times to make sure they're there and then bed them in (instructions usually on the box. If not then take it for a drive going to 50km/h and slowly brake to 5-10km/h. Drive for about 100m to let them cool a little and repeat. Do about 8-10 stops like with increasing pressure each time until you're braking quite hard for the last couple. Drive a little further between stops just to let the brakes cool each time.



Or if its a stone, just pull it out

Thanks for your replies. But I shouldve been a little more specific...

It basically can be heard mostly when at a complete standstill when pumping the brakes hard. The noise seems to be coming directly from the caliper itself, not actual squeaking from pad on disc. My pads arent that low yet.

Hope that makes sense.

Tould be a case of someone skimping on brake pads. There is one brand inparticular out there that I wont touch, they grind and squeal and glaze very easily. Stopping 1500kg of GT4 is not something to be cheap about.

Hi,

If its making a noise when just depressing the pedal Id say the Caliper slides are dry or partially seized, The best lubricant to use on pad backs and slide pins is Coppercote, If you havent got any....grease will work fine. If the slides are really bad you may have to clean them up with emery tape before the coppercote is used.....Watch the ABS Sensors!

hope this helps some!

It may be something simple - dry bolts holding the calliper to bracket, the caliper should float on those bolts freely otherwise it will wear uneven the pads, the solution remove bolt, clean the surface of the bolt and sleeve (bush) and apply good quality grease on the bolt (check the little rubber boots aswell for holes etc.) and bolt everything back.

I wouldnt use normal grease for your slides, use a high temp coppercoat anti seiz (sp?). The grease can detoriate fast with the high temp. Esp true if your a heavy breaker.
