My apology if this is the incorrect forum for this question but I could find no other threads on brakes elsewhere.
I have a kit car that uses twin leading shoe drum brakes on the front, single leading shoe drums at the rear.
The problem was that the car was over-braked at the front. The front wheels tended to lock very easily. Other owners of this type of car had the same problem, one owner told me was considering fitting a bias valve to limit pressure to the front. I had considered replacing the front drums with discs, to get away from the self servo effect of TLS drums. A lot of work though.
I very recently had the idea of fitting larger diameter rear brake wheel cylinders to increase the effectiveness of the rear brakes. This seems to have worked well, the car now brakes much more effectively without the "front-ended" bias.
The larger cylinders were listed as an alternative part for the car that donated the brakes but it appears, were seldom, if ever, fitted.
Are there any snags with doing this? If so, what should I be aware of? I am aware of the likely increase in rear shoe wear rate but is there something else I have missed? The pedal is fine for both feel and travel.
