All handbrake components on the MGC are the same as those used on chrome bumper MGB models, with the exception of the handbrake cables and their attachment clevis pins. The cables differ between steel wheel and wire wheel cars owing to the different rear axle drive flange widths, the wider steel wheel flange requires a shorter cable run to the brake operating levers.
When ordering, specify whether the car is fitted with steel or wire wheels to ensure the correct cable length is supplied. Two clevis pins connect the cable to the rear brake operating levers, one on each side.
Cable Routing and Adjustment
The handbrake cable runs from the handbrake lever on the right-hand side of the transmission tunnel, beneath the car, to a compensating lever at the rear axle, where it splits into two branches connecting to the operating levers on each rear brake back plate. The compensating lever ensures that both rear brakes receive equal force when the handbrake is applied, regardless of minor differences in cable stretch between the two sides. Cable adjustment is made at the handbrake lever end, the cable should be adjusted so that the handbrake holds the car securely on a moderate gradient with the lever pulled three to four clicks from the fully released position. Excessive travel indicates either cable stretch or rear brake shoe wear requiring attention.
Shared MGB Components
For all other handbrake parts, including the handbrake lever, ratchet mechanism, grip, compensating lever, mounting bracket, and associated hardware, the MGB handbrake section of the catalogue should be consulted, using parts for the chrome bumper era. The handbrake lever was the ordinary ratchet type with thumb-button release, mounted on the right-hand side of the transmission tunnel. On the MGC, the handbrake assembly is identical to the contemporary MGB's, with only the cables differing to suit the Girling rear brake drums rather than the Lockheed drums fitted to the MGB.
