Massive brake humming when braking from 100mph

[TomEdwards]

When I'm travelling at high speed (100mph) and apply the brake I get a lot of judder through the steering wheel and large humming noise.

This only happens at high speed.

Any ideas?

Warped disks or seized slider are possibilities

How can I find out?

Id take a guess at warped discs considering ur sayin u get alot of brake judder, if ur gonna brake hard from high speed invest in some good discs that will last longer

Jack it up and take the wheels off.

maybe lack of cooling to the brakes. how many laps and what circuit are u on?

Fred found this to be near side rear disc. It was fitted incorrectly and wonky. So the disc is knackered as well as the pads.

The rear disc spacer washer thing has collapsed as well as the bearing.

So just a new rear brake set both sides

Perfectly worn rear disc :dapprove:

Bull Ring full circuit so including M6 and M42

Pads or discs might be glazed so the friction isn't there. I get this on track after about 10+ laps. That's with ds2500s. Cooling would help. We assume this is on track yeah
