Converted my 1980 clubman from drums to a 7.5'' conversion using original cooper s discs/calipers, fitted goodridge lines all round aswell, No servo on a split system, Brakes are not great for a start, but if i emergency stop the fronts will never lock up but the rears do, Even if im in traffic and a little firm on the brakes. 1 rear wheel will skid.
What rear cylinders shall i buy that might help the situation?
