GQ Rear Diff hot brake

Post by workmonday »

While in the bush today I lost feel in the brake pedal and had to give it a few pumps to get em back. I found the rear left smokin, the wheel, caliper etc was steaming. I pulled the caliper and disc off and found bugger all. Could it be the axle bearing or is it just the brake dragging? Any ideas?, cheers

You make a trip through water at all prior to the steam incident? If so thats probably the cause of the steam...

But sounds like it may be a bearing... jack it up and give it a shake does the wheel move? If so thats def a bearing.

Check all four corners too, just because it was steaming does not make it the cause of the soft pedal...

I should have said it was smokin, not steaming. I think you may be right with the bearing idea. I havent done one of them before, hope its nnot a prick., cheers

Just take it slowly, research the tools you need first... With the right tools the job isn't too bad.

Sticky slides

Post by workmonday »

Yes it turned out to be sticky slides, there was a grove worn around one edge of the slide, sanded it out and rotated 180 degrees and no more sticking. Thanks for your help fellas.
