Matt306 Posted July 13, 2022 Share Posted July 13, 2022 Hello all. I am fitting a brake upgrade to my TR7 I have found some SD1 vittesse calipers which rimmers base their upgrade kit on . Now I could purchase there vented discs but they are Pricey and I suspect they have the rimmer mark up. Anyone any idea what discs they are Quote Link to comment Share on other sites More sharing options...
Beans Posted July 13, 2022 Share Posted July 13, 2022 Tricky one. Many years ago I read that with the SD1 Vitesse calipers you needed Toyota Supra discs. But as I use a different set up up on my cars I haven't got a clue what other work is required (spacer, redrilling etc.) Quote Link to comment Share on other sites More sharing options...
Steve AKA vitessesteve Posted July 14, 2022 Share Posted July 14, 2022 Have a word with EBC they do lots of brake kits. I assume you are running bigger wheels as you may find fitting bigger brakes a tight fit or impossible without them. Quote Link to comment Share on other sites More sharing options...

Matt306 Posted July 16, 2022 Author Share Posted July 16, 2022 Rimmers supply it as a kit damned if I know what the disc is though although the TR7 upgrade book gives me a clue on size etc but not where from. Also the sd1 calipers have three bleed nipples how does that work Quote Link to comment Share on other sites More sharing options...

Some larger BL cars of the day had four-pot calipers plumbed with two hoses to both circuits of the brake system. The idea was that a loss of fluid in one circuit would take out only one rear, leaving both front wheels with brakes, albeit at reduced efficiency as each was only using half the caliper. Since the TR7 doesn't have the plumbing for that, the conversion needs to couple the two independent halves of the caliper by feeding one half from the bleed nipple port of the other.

Matt306 Posted July 17, 2022 Author Share Posted July 17, 2022 I have had a look at some pictures of 4 pot calipers and it certainly appears a couple of pipes are feeds. I'll get some pics of my rusty calipers to show you. Quote Link to comment Share on other sites More sharing options...
