BMW Repair Questions? Ask a Mechanic for Answers ASAP
Hi, my name is***** your mechanic automotive expert, and I will be happy to assist you today. In some cases, I may need more information to assist better. I apologize for any delay.
I try to be here most weekdays and some weekends. If you respond and I do not respond back right away I will do so as soon as I can.
Dear customer, have you performed maintenance recently to the brakes like replacing pads?
Dear customer, I understand your query and I am worried that you have not been maintaining the brake system lately. What i want to explain to you is that through an obd equipment it is very likely that you do not have error codes this because the obd equipment does not throw error codes concerning the ABS system because they do not have access to the ABS module.
Now dear customer, this fault worries me because you have run out of brake and you have a very important feature that is that the brake was placed very hard on the pedal and this happens many times when the servo is defective and does not have the ability to generate the pressure,adjust the braking system so the pedal gets hard due to pressure problems.
What I recommend you first is a review of the atarting sytem with the brake pads then a verification of the connections in the calipers and a review of the state of the same, if all this is correct and there are no problems in the system, there we proceed to a verification of a joint servo with a maintenance that consists mainly of a replacement of the internal rubbers that is common to be damaged over time causing this type of problems accompanied by this type of noise
I recommend you verify this as soon as possible to avoid accidents because there is no problem when this type of problem is stopped or at low speed, the problem is that the system can fail at a high speed or at a time where you require a hard and fast braking.Do you understand me dear customer?
Dear customer, as you will understand i can not determine and from my position if it really is a characteristic noise but very probably it is not as I do not remember a noise when braking or being in D.
In addition, if the brake was placed so hard once this is concerning, it is why I insist that it is best that you do a good review of the brake system as indicated previously and also its maintenance to the brake systems and it have to be checked and maintained regularly and from what I see you have time without performing this type of maintenance it is very likely that here is the inconvenience and with its normal maintenance the problem will be sorted.
