Juddery brake problem - Help sourcing parts please

[NevS2]

Hello all, I'm hoping someone can help me with my 1990 S2 which has just failed its MOT due to fluctuating brake pressure on the nearside. We thought it was a warped disc but having got it up on the ramp to replace the same it appears to be a problem with the hub, flange or bearing. My mechanic tells me we need the whole hub and flange assembly or at the very least the flange and bearing. Does anyone know or can suggest:
a) Where I might source the parts
b) Whether the parts are TVR or come from a donor vehicle and if so which donor vehicle that was
c) Any other comments/suggestions that might help
Any direction gratefully received as I'm very keen to get her back on the road whilst the sun is out! Many thanks
Karl

Phillpot - thanks for that. I'll start searching to see what I can find. I'm in Chesterfield, Derbyshire...I'll check with mechanic to see if he can answer the thread question

Griffinr - It sits in my garage over winter each year...discs are about 4 years old...outside face of disc looks fine but worth a check on contact surface and thickness issue...appreciate your comments thanks

GreenV8S, Phillpot, V8s4me and AutoAndy - I really appreciate you taking the time to share your knowledge and experience....I'm going to head back down to the workshop first thing Monday morning to raise all of the points made and hopefully make some progress. If need be Ive got the hubs on eBay in my sights! Cheers fellas

Thanks Chris I will!

Just a quick courtesy thank you to everyone who took the time to contribute to my post, particularly chrisgadd and phillpot... My S2 now has fully operational brakes and a valid MOT to keep the authorities happy.... All we need now is a prolonged spell of summer...enjoy your motoring. Cheers

Ended up changing the whole near side hub and flange assembly. Mechanic maintains it was the flange probably 'bent' previously when someone replaced a wheel bearing!
