Today i noticed my RHD YJ pulling to the left. On braking it pulled to the right. Tyres ok. So i jacked up the front end to find the passenger wheel was really hard to turn. I removed the wheel and it looked like a sticky caliper. This would on occasion explain the drivers front wheel locking up on hard braking?? After cleaning etc i re-assembled. Finding it nearly impossible to bleed the system. (Will retry tomorrow)

As i put the wheel back on and did up 1 nut (not too tight) i noticed that the wheel was starting to seize. I removed it to check that nothing was making contact and that i had assembled everything correctly, also checking that the caliper slid on those runners for brake compensation.

The wheel went on making sure that every nut was evenly tightened. Seized???

I have no idea. When it was off it is fine. Could it be a collapsed wheel bearing?

If anybody has any ideas i would be grateful.

Take the caliper off and reinstall the wheel to see if it is the brakes or the axel causing the problem.

It sounds like like you had a sticking caliper on the left (passenger) side. If so, then when rolling down the road, without braking, this would cause drag on the left side, causing the vehicle to veer to the left. At the same time, the brake pads on the left side would become quite hot, and their braking efficiency would decrease. So then when you applied the brakes, the right side brakes would work better than the left side brakes, causing the vehicle to pull to the right.

I agree with the previously stated hint of jacking up the front end, removing the caliper (no need to remove the hydraulic hose), tie the caliper up out of the way, and reinstall the wheel. Then turn the wheel by hand to see if if now turns freely. If it now turns freely, you likely have either a bad caliper or a severely warped brake disc on that side.
