I've ordered a new set from Canley Classic.
Should be arriving tomorrow.
I assume the only way to get the bolt of is the old mix of brut force, heat and penetrating liquid?
Any other tips?
Keeping the brakes on after a few hot laps may tend to do that however thick the discs. Easily done in the excitement of it all.
Back in the paddock keep off the brakes.
I'm not sure on the protocols at tracks in the UK these days, but here in Canada they will flag the session as over and you then have a full cool-down lap before coming in. During that lap no passing is allowed, the aim is to complete the whole lap without touching the brakes at all, so easing off to take the slowest corners at 50-60km/h and cruising along at 100 to 120km/h around the rest of the track. The brakes are usually down to normal road temperatures after 3km of no brake usage on the tracks I go to.
On the track I was careful to take a "slow" lap before going for a rest.
The lap at Abingdon is short, so maybe I didn't allow enough time for them to cool down enough.
I knew not to put the handbrake on
It was my first proper track day, all part of the learning curve
On sessioned days a cool down lap would be normal after the chequered flag - on an open pit lane day, it's up to you (it's certainly something I try and do, but you need to be even more attentive to mirrors!). The difficultly can be a red flag, particularly if it's near the end of the lap - but there's nothing you can do about it, other than maybe drive slowly down the track access roads?
I've received the disk and the near side was done within 1/2 hours not issue at all.
But the off side is much more problematic. It's not the four bolts holding the disk on it's the vertical link which is not moving.
Anyone around OXford has a press?
What are you trying to do with the vertical link? Are you not undoing the wheel bearing and pulling the hub off the stub axle?

Caliper bolts out, support caliper.
Hub nut off, remover bub with disc,
Remove 4 bolts, knock the hub thro the old disc
The upright and stub axle remain on the car
