Rear Brake ABUTMENT Replacement - BT-102A

This is an interesting modification for the rear brakes on the MGA. It is possible to install the MGB rear brake adjuster assembly in place of the MGA rear brake abutment. I believe you need to drill one hole in the brake backing plate a little larger. Aside from replacing an MGA part that may be N/A (not available), it can give a second method for adjusting the rear brakes of the MGA. This may help if new brake shoes are to small, or if the drums have been re-machined too large (refer to prior page).

At right, MGA rear brakes with MGB abutment/adjuster. If you do make this modification, as usual keep good records and keep the records with the car for future servicing.
