Upgrading Wedge brakes

[CerbyT]

Another question. Just got off the phone with Tower View Race Services who have a new 300mm Wedge brake kit coming out soon. Unfortunately it looks like its going to be around £650 which I cant afford just at the mo!
So I've been looking for an interim solution. Managed to find some Granada disc on Rally Designs web site that are grooved and x drilled. However they seem to suggest that the size (72-85 reg Granny) is smaller(I think it said 263mm) than the 269mm quoted in the "bible" - help!. Next problem will then be upgraded pads and braided hoses - any ideas guys?

Oh - it also says that price is per pair and it also includes vat and delivery.

Bargain.

no point going massive on teh brakes unless you have a 300bhp firebreathing monster.

we raced last leason in the TVR Challenge on std vernted discs and good pads and never had a moment's trouble. In fact we're racing in the big HP class this season and don't expect at this point to have to put bigger anchors on at all!

We run Brembo discs at 50 pounds a pair and they lasted a whole season racing and about ten track days. The pads also lasted the whole race season.

If you're just driving on the road and occasional track day spend your money elsewhere .. the std vented front set-up is perfectly ok. 650 pounds for an upgrade is frankly a waste of money unless you have a *seriously* rapid car with really sticky tyres.

Noted with thanks - mainly sprint racing, the odd track day and some road use is my normal yearly playing!

But upgrades do look nice which is why most people fit them ..

A few questions...

What calipers did you use?
What size (dia) wheels do they fit?
What size (dia) disks,
Where can I get the disks (part number/description)?

Many thanks
Leo

Just a thought....were the MkII Granada callipers the M16 calliper? Because if they were thats the same calliper that was used on the Capri which opens up a much wider pad selection (used to sprint race Capris but the doctor says my recovery is going well!). Does anyone know?

Any where sell braided brake hose kits for the 350i?

[AM400]

RT Racing stock the brake hoses.

My 350 has single pot calipers on solid disks. So I'd need new calipers to fit the thicker vented disks?

Where did you get your Brembo disks from? Would they do suitable calipers?

Thanks

i've also got a 350i with solid disks and would like to upgrade to vented disks, without having to limit the beer consumption for the next few months. What's the best option?

If i do a couple of laps at zolder and enter the paddock, the brakepressure drops and i can press the onto floor.....

The uprated granny disk is not an M16 and you will need the bigger calliper because of the increased disc thickness. You can get them sometimes on ebay or from a scrappy but very good idea to strip and reseal them as the condition could be iffy. Alternatively get an exchange set. Armed with new discs and pads and callipers and there will be a performance increase but still pretty inadequate IMHO even when I only had a mildly tweaked 3.9 in the car.

Bear in mind that the Tazzie cars are considerably lighter than the road cars and this could explain why they can last out. Now doubt Joolz will claim that I brake aggressively

[joospeed]

Lol .. novice drivers always brake more than they have to Steve ..

After watching the DVD - it's looks like you prefer either oposite lock or max G deceleration

Have watched the thread with interest as, even though I haven't had my car for long, I have come to realise the brakes are only just adequate. (Tasmin 2.8).

OK, so the Granada Mk2 vented discs are a straight fit, the calipers will be also but do I gather there is an issue as to whether the assembly will fit inside the standard 14" wheel without fouling? If it does foul, what's the fix? Thanks,

[grahamw48]

Didn't mk2 Grannys have 14" wheels ?
