60mph Vibration and red hot front right Brake?

[Conor D]

After I bought the car I found on a few occasions that the front right would lock up much quicker than the front left if under hard braking. I took the car out today and was getting a vibration when travelling at about 50-60mph, if I slowed down and applied the brake I still felt it but the frequency seemed to decrease as I slowed.

I pulled the car into the nearest petrol station to check the air pressures and the front right brake was red hot, so hot that the heat went to the alloy itself and I burnt my hand off it; front left seems to be okay.

What's the most likely issue here, warped disk, scrapped pad? When I arrived home, it smelt as if I had just done a 20 minute session on the track.

Seized brakes?

Similar issue, smell hot metal when I parked up - seized brakes.

It's caliper rebuild time (piston's not sliding)

Might be muck in the brake pipe, this sometimes sinks to the lowest part, the piston, and seizes it. New brake pipes and a change of fluid may cure the problem.

Is it a big job to put right, and does it generally require any new parts?

I'm leaving the car with a Mechanic some time this week to fit coilovers, and I'll get him to have a look at this too.

Also is the vibration normal, or would that suggest warped disks?

It could just be rusty slider pins, or crap on the slider clips, a good anal strip down,clean,and rebuild is needed with red rubber grease for the slider pins once rubbed down of any rust build up,and copper slip for everything else,but do them all not just the one corner,bleed off and enjoy her braking straight

What they both said

Same problem here, same corner, I've just finished stripping and rebuilding all of the calipers, not too difficult if you have the Rod Grainger manual, got any parts I needed from brakes international online.

There's a great youtube video of how to re-insert the piston and seals into the caliper, this is the tricky part in the whole process.
