BRAKES_MR 47 When the foot brake is operated, both the shoes are pushed on to the drum by the wheel cylinder plunger. As the shoe linings wear, the outward movement of the shoes exceeds a predetermined amount and the pawl pivots on the spring dowel to rotate the serrated nut. This action lengthens the adjuster assembly sufficiently to reduce the clearance between the brake shoes and drum to the desired minimum. The adjustment is repeated, whenever necessary, according to the rate of lining wear. 13.7. REMOVAL AND REFITMENT OF REAR BRAKE ASSEMBLY Removal Procedure 1.
