Hi every1. First of all just wanted to say that is site is excellent!! feels good to know that there are other BMW enthusiasts out there. Cant wait to post pics of my car on the site!!

Anyhow, just wanted to know why i get sqeaky noises when i brake. I've recently change all the brake pads but the problem seems to be persistant. Could it be the discs themselves? i feel along the edge and their seems to be sights "bumps" on the discs. Do i need to get them machined or do they need replaced. I'm from Australia and wondering which one is cheaper to do.

Also, i find that when i brake, its not a "steady" brake but rather a sorda lumpy brake...could there be air in my brake system or signs of sumthing for cynister?

Your help would be much appreciated!!
Cheers.

first off, welcome to bimmerwerkz, glad your here to share your love for BMW;s.....


secondly did you do this brake job yourself? if so did you remember to resurface the rotors? and if you did , did you make sure that there was sufficient rotor left to run on? that could very well be the root to the unsteady braking patterns..

for the squeeling, im curious as to what pads you used or went with. and if you took the time to seat the pads properly... normally when you get new brakes its a good idea to take the car for a few good stops right away, its seats the pads properly ..


whats happening, for those who may be curious is , the brake pads all have a resin that is part of the pads, when the pads "glaze" the resin acts much like the resin on the bow of a violin.

dvmotorsports is on a distinguished road
Were the shims already on the pads or were you supposed to put them on yourself?

If the later, did you remember to add the shims?

hmm.. the pads used were called bendix. I got a mechanic to install them. I think he just changed the pads. SHould i check the rotors for thickness? how do i resurface the rotors? Also what are shims? As you can tell i'm pretty iliterate when it comes to cars and how to fix them. SHould i just get the rotors replaced?

your help is much appreciated.

the mechanic should check thickness , most do just so they can soak you for the extra cost. resurfacing basically you take the rotor and even out any rough, or taller spots on the rotor , usually mechanics use the air tool with the automotive scotchpad on it. (trying to describe it as non mechanic talk as possible hehe)
