I have a 2012 Range Rover Supercharged. I have some front wheel vibration when i brake over 50mph. I posted on some forums and got feedback that I may need to replace my front rotors. Did some research and ordered new front brake pads and rotors. I jacked up the car today to find out that the bolt holding one of the rotors seems to be missing on the driver side.


Picture of Passenger side rotor --- Looks good:

Driver side rotor -- Looks like its missing a bolt

Is there another place where the bolt is supposed to be? Should I be looking somewhere else? How do I get the rotor out? I have tried hitting it with a mallet but cannot get it to come out.

based on the missing bolt picture ,
the rotor was not properly aligned with the threaded hole on the hub flange.
NOTE in that picture you dont see any threaded hole or broken off bolt, just the hub flange.

To remove the rotor with minimum hammering and possibly damaging the bearing, from excessive force.

Spray some PB blaster on the rotor face so the fluid will wick into the stud holes and the hub mounting collar,
let it soak for a few mins,
then get a MAPP gas torch and heat the outside area of the rotor hat,
about 200 degrees should be sufficient for the rotor come off,
hit the rotor from behind and it should come free.
get a new shouldered bolt to hold the rotor on the hub.

NOTE a missing rotor bolt will not cause a wheel shimmy.

NOTE you should have all 4 of the wheels checked for balance,
and make sure the wheels are fitting snugly on the hub collars.

NOTE if your wheels dont fit the hub collars,
then alignment collars might be needed to center the wheels on the hub flange

where are you hitting it with a mallet? If you smash it on the hat (not the rotor) it should eventually pop off. Or if you have an impact hammer with a blunt bit just zapping the hat in various places should also break apart all the rust holding it on. Otherwise what mrmerlin said! then during refit use antiseize so it isn't a problem next time.

Thank you for the information. I got the rotor out after couple of tries of torching it to 200 degrees (2nd try). I was hoping for a broken bolt but it seems like the technician just didn't bother to put it on.

Working on the passenger side now. It has the bolt and I took it off but its still not waiting to come out. Sprayed some sea form deep creep and will try to use your technique again tomorrow.


Ordered a set of 4 rotor bolts from Atlantic British. Hoping to get them in the next 2 days so I can put it back together.

Update for everyone.

Got the second rotor out as well. Used this guys bolt technique that turned out to be a much better method than banging at the thing. Worked like a charm. Rotor came out in a minute with no banging.

Replaced the rotors and brake pads. No more vibrations while braking.

Time to finally get on the road and burn some rubber.

Thank you all for your inputs.
