Help needed with brakes

[Darkspeed]

Blimey, was that really 17 years ago!? And here's us not a day older. Or wiser.

Good find Chris J.

What's the Litton pedal ratio? Most aftermarket pedal boxes seem to be about 6:1, Hawk's is poor on that.

Tilton in the Litton measures as 6:1 and had .750 m/c's fitted with the stock Scorpio brakes - no idea if that is right wrong or sideways or how good the pedal was as I can only comment on what I have removed not how it worked.

I originally built my Corse I with this setup (Tilton pedals and Scorpio brake calipers/discs). I can describe them as barely adequate - slowed the car eventually with no real 'bite'. I've since changed to the Hispec setup from Craig with large disks (330mm I think) all round - it was transformational. Car now stops as agressively as needed with tire grip being the limiting factor once the pads have heated up (EBC yellow).

I do remember talking to Mick (Catswhiskers) about brakes when building my car because he had Alfa calipers and Tilton box on his Corse - he told me that he installed a remote servo booster to improve performance

Finally sorted !!!, I changes to BMW 316 disc 290 x 22mm which moved the disc inwards and allowed me to fit the Hispec 4 pot calipers. Now I have a brake, with a real good bite as soon as you press on the pedal without big effort. My conclusion from this is, its very difficult to get a good brake from a sliding caliper with a piston size of 56mm without a servo.
What I have ended up with is Disc 290 x 22mm Four pot calipers with 34.6mm pistons, Front master cylinder .625" and pedal ratio 5.2 :1 and loads of smoke out of the front tyres

And a healthy dose of confidence too, eh?
Well done for the perseverance.
Have you got a part reference for the discs?

Did that need a custom caliper mount Gerard?

John / Chris,
I tried to upload two photos , no luck with that so far.
I used a pair of second hand disc I got off a 07 BMW 316 and the calipers I took of a rally TR7 which I bought last year for breaking, Made the mounts myself so spent nothing
I can get the part number for the disc if required

I like it! Makes a refreshing change from throwing as much money at a problem as possible which seems to be the current trend.
I guess the disc is easily identifiable enough from a database such as Brake Parts International.

Sounds like we best hold off on that carbon ceramic disc and 6 pot upgrade just yet eh Jim??

I was happy to pay all the money for the carbon ceramics since it should keep the brake dust down.
I guess it should make the car stop better as well but that's a secondary concern.
