Front brake rotor bent

Hello all,
I had a brief encounter with a minibus as a result my left front brake disc is damaged. The central part which hold the brake disc is damaged and its grinding the brake pads.

I had it checked with local BMW.
Q1: They reccomend replacing both of the disc as ful set. The claim is if the change only the damaged one the play levels will be different and the steering will jitter in heavy braking.
Does any of us replaced a single front disc? What was the outcome?

Q2: I found out that GOLD makes front discs for F800GS. Does any of us used any products from GOLD? Would you advise them?

I will share my decision and its results with the community later on.


Thanks.

I haven't replaced any disc and I don't think it necessary to replace both unless they are worn to the point that they need replacement any way. The Hydraulics will sort it out.

Galfer, EBC and Bike Master, all make replacement pads. I always use Organic, because there is less wear on the rotors. But I am not a hard user of brakes.

More info

The bike has 13.000km on it. That is 8.000 miles.


And I have used different brake pads from various manufacturers and they worked ok on previous bikes. But here the issue is the brake rotor or disc.

13000km is not a lot of wear, under normal conditions.

I'd be tempted to replace the damaged one and then wait for the OEM to require replacing and do both at that time.

So long as the break callipers are not stuck, the slight difference in thickness shouldn't really make a difference.

I'd pull the plate out of the body and grease the pins...they do stick!

Tell us where you are. An inmate has an OEM spare front rotor he might be able to ship out.

I bent one rotor with a deer strike a few years ago. I had over 15,000 miles in the bike. I replaced only the bent rotor.. Never a issue..

I just replaced my front rotor with an EBC disc. It was about half the cost of the BMW one.

Thank you for the valuable feedback. It looks like I will do the same as well.

This is interesting. We have looked at the EBC catalogue and there was no listing for the F800GS front rotors (discs). Are you sure it was EBC? Could it be a different brand or the rear rotor?

Motorworks.co.uk offers Brenta and louis.de has Brembo and Lucas discs. You can check them, too.

It is an EBC disc for the front of my F650GS. I just looked at the site I bought it and they don't show a disc for the F800GS. So that won't help you. Seems weird that they have a disc for the F650GS but not the F800GS.

The 650 disc fits many years, models and manufacturers. The 800GS disc fits the 800GS.

The Verdict

I would like to share information about the latest status of the bike.

After reading Smitty141 and other data it looked I do not need to change both of the discs. This also meant I was mislead by the only local service center of BMW in Istanbul.

I have called my mechanic who used to service my DL1000 (yes he is authorized service for Suzuki and Sym). I have explained the case. He said he will lok at it. He picked the bike since I was at work. This was all in the morning.

He called me at noon to tell me the bike ise ready to be picked up!

I stopped at evening on my way home. Asked what he has done. He told me to take it for a spin and test it.

Well I surely did that with busines suit. I have tried to brake hard only with the front brakes. Sure enough at the second try the ABS kicked in.
So I disabled the ABS to see if there was any shakes or instability at the steering. I managed to lock the front disk and almost lost control. But looks like it is working fine. All the tests were done at 1st and 2nd gear, bringing the bike full stop. I do not recalll what speed I was but surely I gave it full instant brake.

When asked he has exolained that the he took the discs to special brake shops. They fixed it.

I will further test it this weekend and share my findings with you.
Again thanks for all the information and sharing your experience.
Regards
