Front brakes replacement needs to replace rotors?
Took the car to the dealership and was advised the front brake pads required replacement. But was in awe, when got told the rotors need to be replaced as part of the exercise?
This is the first time, I've ever needed to replace brake pads with BMW. I've owned Volkswagen in the past, and never once I had to replace rotors. It was only ever replaced, when it gets severely warped. But nothing a bit of machining couldn't fix. Can someone advise if this is a standard practice with BMW? |

That wasn’t the case with mine. They resurfaced them.

- your driving environment is one which requires excessive braking (very hilly) - you are in the habit of heating the brakes (say a long descent, or frequent hard braking) to high temperatures followed by a stop (keeping foot on brake), the discs in contact with the pads then cause uneven cooling and warping. - you drive in a very harsh environment causing accelerated wear (this includes salt corrosion, silica sand etc) I think you have every reason to be suspicious, it is an easy and major rip-off item to add to a service. |

On my last few cars, I have always replaced the rotors at the same time as the pads. Although not always necessary, I request and pay for replacement of the rotors because brakes are important! To me, it is part of the cost of maintenance and personal piece of mind.

Yea what's your mileage? Typically rotors do not need replacement when pads are being replaced unless you have well of 50K miles as someone else mentioned. I've had rotors last over 100K miles on my Volvo's.

The milage is only 34000 KM, I definitely suspect this is a rip off item.
When the brakes are required to be replaced, I am thinking of taking it to a workshop rather than dealership. Since all logs are stored electronically on the key fob, I am not sure if any workshop has the technology to do the same. |

I recently replaced my brake pads, not the rotors, on my e88 (admittedly a quite different BMW) at a little over 80,000 miles. The brake light had been on for some time but I checked the pads and they still had a lot of wear left. The sensor is quite thick so it gets touched and lights up the light when you still have around 1/4 inch of pad left. That is probably over 10,000 miles of material at my usage rated but I got tired of looking at the light in around 5,000 miles.
I got my drivers license in 1971 and have always maintained my own cars. I believe both machining and replacing rotors is usually unnecessary. I treat my BMW the same as my Japanese, American, and Korean manufactured cars. As long as the rotors are still thick enough and not damaged, I just put on new pads and go. The reason that repair places do not do this, however, is a little bit safety and mostly complaints. The safety angle is the fact that the pads have to wear a little bit to have full contact with a used rotor. So your stopping distance is slightly longer for 100 miles or so. I very rarely make panic stops so I do not see this as a big deal. The bigger reason is the brakes may also make a little noise until the pads have made full contact. Again, not a big deal to me. But a lot of people complain loudly if their brakes make noise after a repair. So my point of view is if you are willing to allow a little more distance in braking and ignore a bit of noise you can just replace pads. But getting a repair place to go along may be difficult. They get paid for their time which will be wasted if you come back complaining and they have to take things apart again. It is your money, not theirs, that gets wasted on the unnecessary parts replacement. By far the safest way for them to go is with new parts.

discs I have normally found I need to renew the discs for the second set of pads.
The only exemption was a Volvo 850R that consumed a set of discs with each set of pads , and never lasted the miles I had previously or on later cars. That car also consumed clutch's at short mileage. |

3000 miles X1 and the official BMW dealers says rotors need to be changed
Hi
I have a leased 2018 X1 in Montreal, I drive it daily almost within the city, clocked 5000 KM within 18month, in the last few weeks after we returned from a long 3 weeks vacation (car parked outside) breaking became more and more uneven, went on the highway and there it was shaking a lot when breaking. The dealer said it was rust on the rotors that damaged them, and they will charge over 1K cad to replace them. My question is, what the heck? you buy a car, drive it less and it gets defective? Breaks are not covered in the lease warranty, and he said they cannot turn the rotors as now they come in slim 2 parallel pads, 2 he said the alloy now does not have asbestos (??!!) tgus they rust faster... I hope it is not a Volswagen type scam BMW are doing.. any comments? links to similar cases would help.. |

Its easy to measure disc thickness and see if they are within tolerance.
I copied this, On the M Sport discs they start 30mm thick, and recommended minimum is 28.6mm. When my pads had worn out the discs were 29.3mm so they had exactly enough left for the full life of another set of pads. No reason has been given by the poster for the replacement need.

The brakes on the X1 and the fact the 2016's had the older idrive are the two worst parts of these cars. I had my brakes fully replaced at less the 20,000mi for warped rotors and pads. At 31,000mi I'm having the same issue again. I don't ride the brakes when driving. It's not as noticeable around town, however on the highway the car shakes a good amount. I'll be asking them to service the brakes one last time under the 4year service contract (which does cover brakes on the 2016). I'm sad to hear the newer model years are still having the same issue so I can't expect this to be resolved when the brakes do get serviced again.

Had mine a month now and have noticed the gearbox is in a coast mode when the accelerator eases off as the rev counter drops to idle even though the car is doing over 50+ mph. Press the throttle and the rpm goes up to 1500. The upshot is the brakes are used more because of less engine braking. Maybe thats why the brakes are wearing more than normal on some members cars.

Discs, (rotors) are made of a relatively soft material as this makes the brakes more effective...........they are supposed to wear...........not like in the "old days" when they were as "hard as iron"
Depending on your driving conditions timely replacement of the rotors is not a bad thing to do and should be considered as preventative maintenance............ they are not (relatively) that expensive......... but it's a BMW so nothing is cheap Just ask to see the wear marks on the rotors if you are suspicious |

This was my reaction too. First scheduled pad replacement and was advised rotors had to be changed too for a nice fee of $2.5k+
I did almost 40,000km and the rotors were actually under the minimum thickness. Given my car is still on warranty, I did not want to take any risks by not getting them replaced because any accidents/failure relating to the brakes could be used against my claim. These rotors definitely do wear quick. Pretty shit but it is what it is. I did it independently for half the price. I note you are in Vic so if you want to know my mechanic, feel free to PM me.

I got a set of 4 (front + black) rotors and ceramic pads for $320 usd from R1 Concepts. Only replaced the rear so far, but looks much better than OEM with the slots and drilled holes. I can’t tell any difference in braking either.

The parts - discs, (rotors) and pads should not cost anymore than £300 for all 4 hubs
Not sure what BMW charge for the parts, but just used the internet for US suppliers https://www.carid.com/2018-bmw-x1-pe...-brake-rotors/ A DIY job is not difficult and should not cost that much even if done by your local garage |

When they replaced my front brakes and resurfaced the rotors, I started getting an odd squealing sound at low speed and took it to the dealership 3 times (First time they couldn't replicate, I took videos and showed them, they replaced the brakes again, then they replaced brakes and rotors), it ended up being the rotors that caused the issue - after they replaced them, the sound went away. But, I'm sure you could persuade them to check about resurface vs replacement - I've found when push comes to shove they'd rather have your business versus not at all (at least the dealership around here does) |

They said it was only an advice to replace the discs. Because bmw gives an advice to replace them when they reach a certain thickness. They could only replace the pads but then i would be back within a few weeks to complain about sqeeks and crackling from the pads. This all set me back €980,- |
