2004 545i Brake Vibration - BMW Forum

mqt1969 · 01-10-2010, 01:23 AM

THANK YOU IN ADVANCE: I replaced all 4 rotors and pad at same time. They work well then 2K miles later braking started to vibrate. I had front SLOTTED rotors resurfaced and it corrected the problem for about 1K miles then vibrated again. Worse vibration is at about 40 miles per hours but if brake hard then hardly any vibrations. I then replaced BOTH front rotors and pads with NON slotted rotors and again, all is fine at 1K miles then starts to vibrate again. This is getting expensive and very annoying. PLEASE PLEASE HELP. I also had the brake oil changed but still same problem.. thank you

maybe not the brakes at all but the thrust control arms, when the ball joint or the bush wears then as all the weight of the car is transferred through these two puppies it can feel like warped discs..... they are about $100 each... with the bushes included, or it is possible to change the bushes but you need a press...

To Harryinsaudi: I took the car to the dealer and they test drove it. The test driver said it's because I have after market Rotor and Pads. THEY are harder and cause uneven spots that's why it vibrates. He said factory ones are softer and designed for the car. I am not sure if its true but they recommended Front Rotors and Pads and REAR pads replaced. They wanted 1200usd, I opted to buy the parts and do it myself for 800 dollars. Needless to say, I spent another 1500 for bushings and oil pump leak. Now I am broke. I will be able to verify after about 1000 miles or so if its the OEM product resolves my vibration issue. Thanks for you in put...wish me luck

well good luck with that then.... unless you bought really cheap rotors i can't see why pads/rotors combo can cause uneven spots but hey....

tell you what...I'll try them on mine.... i need new rotors, i've got red stuff harder pads already and no problems at all..... give us a price... i'll pay postage and if they're ok i'll send you the cash or return said pieces of junk....Harry

Hi Harryinaudi: The first set are brembo drilled and I had them resurfaced once and it cause vibration again after about 1K miles. The Pads are Red Stuff. If you want them I can mail them to you but they are heavy have any suggestions of cheaper postage? The second set i dont remember the brand but its regular rotors ( I mean not slotted or cross drilled) Man, they are still like new. I'll be glad to send them to all to you if I can find decent postage fee. If it works out then just give me whatever, I guess we just have to live by each other's words

so far I have about 300 highway miles on OEM parts and seems to be OK and smooth as a baby's butt
