Heavy scoring will require the use of a brake drum lathe to turn the drums.
Turn the drums from both sides of the car an equal amount to avoid uneven
braking. The service limits of the inside drum diameter are as follows:
- ff–1, 1300G sedans: 8 in. (205mm)
- All others: 9 in. (230mm)
WARNING
On ff–1 and 1300G models when the drum is turned, the automatic adjusters
may reach the end of their travel when the brake linings are only half worn.
Replacement of the drums is the only cure.
