High speed brake vibration when they're hot

[stonesie]

As above, I was getting quite a strong vibration from the front brakes on my track day at Cadwell (slowing from Park straight into Park corner) after a couple of laps, nothing at lower speeds or on the road.

Pads are factory fit with nearly 9K on them and I would estimate 60% worn.

Discs look fine, bit of rainbow heat colouring but no visible warp.

Any ideas?

I do remember triumph wanting a dial gauge using when reporting warpage under warranty, anything over 0.5mm iirc they would replace, so you're not likely to see that level of warpage with the naked eye

To either the dealer or eBay then for a DTI...

My 2p.

Used pads might/may have caused vaporised pad material/other shit to condense in the perforations.
It may be causing them to skip under braking heat and pressure.
Clean out the holes in the disc.

I had a bike that would squeal like a biatch when ever the pads were about 1/2 worn.

Just a quickie before you spend a small fortune on new pads.
You'd be cleaning up before new pads anyway.
