MK1 Brake Mods

New discs will put you up faster and wont fade as quickly.

Bigger booster gives a more modern pedal feel (requiring less imput for the same result) and a bigger MC pushes more fluid for greater stopping force.

Plus replacing 30 year old parts with new or newer stuff will make a massive different

A few clarifications

going from solid to vented discs of the same outer and inner disc braking surface (mk1 solid to mk1 GTI vented for instance) wont make any difference to the maximum braking force/decelleration (all other things being equal). what will improve is your brakes resistance to fade as the vented disc will dissipate heat faster.

a bigger booster will increase the pedal sensitivity, reducing the require force applied by the driver (not a bad thing in a Mk1 with the linkages between the pedal and the MC/booster)

increasing the diameter of the master cylinder will reduce the travel of the brake pedal, but make it harder to push (this is because the larger diameter MC piston displaces more fluid per unit of travel)

decreasing the diameter of the master cyclinder will increase the travel of the brake pedal, but make it easier to push (as the piston is displacing less fluid.....)
