This Mitsubishi Shogun came in with a shudder under braking.
The front brake discs both looked OK and measured well outside there minimum thickness.
It was decided to re-surface the discs on the vehicle using our specialised tool that is attached on to the brake caliper mountings.
The left hand side disc re-surfaced fine with only a minimal amount of machining.
When attempting to machine the right hand side one it was noticed that the outer side of the ventilated disc looked true but the inner side looked like it was running out.
After investigation it was found that the ventilation webs have corroded through all the way round and the inner face was therefore not running true to the outer face. Pity we didn’t choose this one to start re-surfacing first !
This was obviously the cause of the brake judder solved by a new set of discs and pads.
