Finally get to drive MY V8S - brakes suck.

Hi Pies,
Hopefully Peter Humpheries, whose 'been there, done that', on S brakes, can offer some more advice?!

Emma, please note if you start taking advice on what you can do to your car from Mr Humphries, you will end up spending a scary amount of money!!
subtlety has never been one of my stronger points, I take it the fact that BG are getting your custom thats a non recommend then. 
1. I agree with Pete about Hispec. I swear by them... 
2. Braking limit is determined by the tyre/road grip. Bigger brakes allow you to get closer to that limit more than once by allowing the brakes to cope with the heat generated. They also can chance the balance so that the braking is more balanced and improved.
3. I would replace the fluid with Dot 5.1 and get some decent pads. See how you get on. It could be that the seals are iffy and letting air in without leaks and this is causing the spongy ness. Just had this on the 520 where the rear circuit would die. Bleed the rears only and the pedal would become hard. No fluid leaks but the rear calliper seals had gone. A new set of seals and the brakes remain hard.
4. If you want some incredible braking, run slicks

Hi Fly Girl
I fitted EBC Grooved and Drilled discs front and rear to my V8s using EBC green stuff pads and the braking was improved dramatically. As they are a ford fitment the price was fairly reasonable too. I believe the discs are called spotties!! Happy Motoring

CarZee has exactly the same on the front of his S as I felt they were a good buy when i owned the car... certainly better than the original setup.
Cheers

only food for thort!! But if your doing 70 and something crazy stops or pulls out infront of you - all the technical stuff stays in the back of the mind and the right foot stays firmly on the pedal.....locking everything anyway. Good brakes are a bonus for everyday driving - but are not any more efficient at stopping in dire emmergencies. IMHO and experience.

Wih practice, you will get the knack of threshold braking. But, however good you are at this, you can still lock up from time to time. When this happens, your instinct will be to brake harder and harder. This instinct is wrong, and you should be cadence braking. This is quite easy to do and the hardest bit is overcoming your instinctive reaction in the first place. Threshold braking and cadence braking are skills that everyone should have, but they require the sort of practice that you really don't want to have on public roads. But once you get the hang of it, you'll find you can recover from that lockup, keep braking near the limit and trail the brakes into the corner to scrub off the excess speed. Which can be the difference between coming out of the corner slowly and untidily, or not coming out at all.
Thanks Peter...am all very new to this!! Kevin has had TVRs for eons, but this is my first beast and the only experience I've had is driving his Chimp! (great fun too!!!) Any advice is very welcome spin:
Not had much chance to drive yet... otter switch bust almost instantly....going in to David Batty for full service next week, followed by a visit to the bodyshop for a little work!! Can't wait to have him back!!
Still can't believe I finally have an S.....gorgeous!!!!!!!!!

Just put these all round on the chimaera with red stuff pads, also put braided lines all round. Brakes are brill now!!!!, The discs are dimpled as opposed to drilled which I think helps to stop the cracking suffered by drilled ones.

Ah the old Brake sucking S thing going on hey?
find yourself an old sierra XR4i in a scrapyard (not easy these days) and rob the front discs off it .. they're Griff 500 diameter, 4 stud fixing rather than the converted 5 stud granada efforts TVR sue as std, plus you get the granada sized caliper that doesn't need a spacer between it and the hub for it all to fit together. i have this set-up on my V8S and it's a cheap and cheerful way of getting more front end stopping. If you go for chimaera wheels with 16s on the back you nca have the vented rear brake option too
How will this affect the braking balance of the car?
