Made the mistake today telling someone my TVR had never left me at the side of the road ...
Driving along the A46 this evening had the brown trouser moment of no brakes. RAC man thought one of the rear brakes had stuck/locked and caused the brake fluid to boil. Disc had some reddish residue on it and was still very hot after an hour of sitting in a layby and you could smell the brake fluid.
If I'm going to get the rear brakes looked at, should I be considering getting them upgraded at the same time. What options have I got?

Sounds remarkably familiar CDT
My problem was caused by a split caliper piston seal causing the o/s rear brake to bind. If you car's anything like mine, it's probably due a bit of an overhaul. I've stripped the back end out of my car to fit exchange calipers with new pads and discs (I don't think it's possible to remove the calipers with the axle in situ).
Whilst the axle was out of the car, I took the opportunity to give the back end an overhaul (I'll post a thread next week when it's finished and back on the road....) which should prevent further problems later on.
There is a Jaguar parts supplier that does a vented rear disc conversion (the axle and rear brakes are XJ-S) but I think it would struggle to fit on the Wedge. The standard set up (if in good condition) is fine, but would benefit from some extra cooling. iirc, R T Racing do a ducting kit to get some fresh air to the rear brakes which should help.
Post up if you need any help!
Yes it is possible to remove the callipers in situ. No need to drop the rear axle or anything like that although some reckon it is quicker... not toitally convinced having done both jobs.
Covered in the bible. Undo handbrake calliper, unbolt and they will come out through the chassis. The vented kit doesn't work as the callipers are spaced and this causes issues with the fitting as it hits the chassis. There is an alternative but it was around the 2K mark and had the disadvantage of not providing a mechanical handbrake.
Tower View made a ducting kit that took air from under the car to keep the brakes cool as I was having heat issues about 7 years ago but the front brakes usually die way before the rears start to be an issue. I had a mega brake upgrade and that caused the issues.

My 280i did that a time or two, just after I got it (it had been standing for over a year.)
A local garage cleaned up the rear brakes for me, for about 40 quid I think, and no more overheating.
I later had them overhauled at RT Racing, actually acquiring a functioning handbrake in the process.
Back to virtually no H/brake on this one though.

I'll tell you a little tale now.
When I wer a young lad, back in the days when cars were often held together with binding twine and filler,
I was pumping away at the brakes for the MOT man, when suddenly, just as he stood up and said "ok that'll do young man"...NO BRAKES...pedal to floor
I hurriedly thanked him for the certificate, handed him my Seven pounds 10 shillings,
and drove all the way back home across town on the handbrake.
Looked under the car, and there it was ...big hole in the brake pipe which ran the length of the car.
A couple of hours and a couple of quid later...job done.
