Inbord Brakes

Has anyone got pictures of or have used inboard bike discs on thier cars?
Is it possible to use inboard brakes on the front, just cant think how that would work???

Inboard on the front is posible but not worth the effort the only RWD example I can think of is the early versions of the Lotus 72, they were later abandoned by Lotus. The saving in unsprung weight isn't great compared to conventional brakes.

didn't some alfa's have inboard brakes with their rear mounted gearboxs ?

a quick google later:

Old rovers and some jags have inboard brakes. I cant see that the complication of designing this into a locost would yield any benefits. What are your thoughts / plans.

The formula ford running gear that I have coming my way has modified triumph herald uprights (no fitting for calipers) and I was toying with the idea of keeping them and going with inboard bike brakes either side of the modified Supra diff I will be using.

Ah Ha, never thought of google pictures

You can't have inbosrd brake with Triumph uprights -- impossible as it has a solid stub axle.
To fit brakes all you need is Triumph GT6, Vitesse or Lotus+2S caliper brackets they bolt on ro the face of the upright unlike Herald/Spitfire ones which are cast in.

well that would save a lot of messing about!!
When the hubs arrive I will post a pic on here to check that they will fit
Cheers

later 2CVs had inboard front disks. Mind you, they were FWD. If you already have a drive shaft, transferring the brakes inboard can save unsprung weight. Adding shafts to do this seems a bit futile.

one of our posters has used inboard rear brakes - was it erwe? Rings a bell...

I will post some pics tomorrow.
I used Bike parts because I also used these on my first car (see avatar).
Until now I had no problems in both the trackdays I did. As you see in the pic I did use an extr air duct for cooling (this one is self made and I wil replace it late with some Ducts) Rescued attachment zx.JPG

Anyone though about using 1 single brake for rear on the prop shaft?

Don't even think about a transmision brake as a service/foot brake --- they went out of use as service/foot brakes in the mid 1920s for good reasons. As a parking brake they have a place (ie 4x4s) but as foot brake they are too fierce and will shake the whole drive line to pieces.
