Wheel shake whilst braking at 90 mph?
Discussion
I know the Oil indicator is not related to brakes!!! You have to be pretty dumb to reach that conclusion.
I just added to info in case any one else had an MIL problem and my experience was of help.
SFR Engineering are amazing at maintaining my Cerbera and would highly recommend them.
Any idea how much a skim of disks will cost?

sounds like warped discs to me. mine cost 75 quid per disc, and was done the day i took the car, at the sellers expense.
BUT any engineering place will be able to do it, its really not a big job. at most 10 mins a side. if i were you, id get it done at a local Eng/ Fabrication place. i had the discs skimmed on both my scoobies (deadly prone to warping cos of the heat) at a local toolmakers and it cost me about 25 quid for both. and even then, it was just a 'drink on me' kind of payment cos it was so simple and quick.
as a tip, and youll forgive me if im telling you wot you already know, but cos our discs arent vented, i would thouroughly recommend against sitting at traffic lights with your foot on the brake, or indeed with the handbrake on if possible, especially after a run. it causes a hot spot on the disc that cannot cool equally, and will pretty quickly lead to wibbly discs.
hope this helps.

If it's JUST under braking, it'll be warped disks...but how you've managed to cook them on the road is quite special, unless they're rather old and tired already.
If it's at M-way speeds only, and regardless of braking and accelerating, it's an unbalanced front wheel.
If it is what people describe as warped disks (though there's a lot of debate over the meaning of warped) Jools can supply you with an upgrade kit that is cheaper than TVR's own replacement parts.
Just had Jools' stuff fitted to mine. Not only do they look the bollo**s but the work seriously well
I've been searching postings and it appears there's some debate if warped discs actually exist. There can be cracked discs or pad residue build up onto the discs which appear to be mistaken for warped discs. There is an article from a guy who worked for Shelby on the GT40 - I'll try and find it again.
The solution appears to remove the discs and sand them carefully with 800 grit wet and dry and clean with brake fluid cleaner. The pads should then but sanded with 40 grit to remove residue.
I've taken the day off and I am going to give it a try. If it doesn't work, I can take them to be machined. Costs a £10 per disc!
Wish me luck.
Cheers

John,
Warped discs DO exist, regardless of some so-called theories. But I do agree that the term "warped discs" is over-used. I should have been more precise earlier.
If you get the faces cleaned, then the only thing that will be left that could give you your specific problem is the caliper, and that's unlikely.

yep, not an urban myth: mine were out by at least 6 million miles a side (a technical term, hope it translates ok to you less mechanically minded folk)
if theyre warped enough such that you feel it under breaking (sufficiently worringly enough to put up a post anyhoo) im happy to wager some 1940s bovril (part used) that the only thing youll achive with fine grain sand paper is a shiny disc and a wasted day off.
dunno how much you get paid, but if its more than twenty quid a day (i dont...siiiiggghh
) just take em to be skinned and spend the day eating cheese on the sofa watching columbo.
go on , spoil yourself. get somebody else to do the work. if nothing else, itll be the only thing youll ever be ble to have done on your car for 20 notes, apart from enough magic trees to take away that delightful 'old boat' smell for two or three minutes.
best wishes,
