SAFARI STORME MY14

BRAKES 15 BRAKES WORKING PRINCIPLE : The Thermoclip is assembled between the adjuster nut and the adjuster push rod. In the brake 'OFF' condition, the shoe return spring forces the shoe webs against the adjuster rods. When brakes are applied the shoes move outward and there will be no force on the adjuster rods. Also the shoe movement makes the pawl to rotate the adjuster nut ensuring adjustment. Around 150 deg. C, the thermo clip opens and the force exerted by the thermoclip will become higher than the force exerted by adjuster pawl at the hinge point. At this condition, the adjuster rods are moved outward and also the rotation of the nut is prevented. Thus the clearance which is caused due to thermal expansion does not result in over adjustment. BRAKE MAINTENANCE Note : The rear brake shoes have to be replaced insets only. If you are replacing brake shoes on left side brakes then the brake shoes on right side brakes should also be replaced. To maintain the efficiency of the brake system, preventive maintenance is essential and the following recommendations should be observed at the intervals stated. BRAKE ADJUSTMENT As it is an auto adjust brakes, brake adjustment is not required. 1. Every 10,000 kms check the lining for wear through the inspection hole provided in the back plate, removing the grommet (35). The linings should not be allowed to wear down to rivet heads. 2. Every 20,000 kms clean the back plate and lubricate the tips of the shoe platforms with graphite grease and the moving parts of the adjuster with mineral grease. Keep the grease away from the shoe lining sand all hydraulic parts. 3. The wheel cylinder should be overhauled once in 40,000 kms or 18 months whichever is earlier. MAJOR OVERHAUL It is essential that the shoe linings are inspected at regular intervals to prevent the drums being permanently damaged and subsequently making drum removal extremely difficult. If the drums are allowed to become scored or grooved, the problem of drum removal can usually be overcome by increasing the clearance between the shoe linings and drum as follows : Caution : As it is an auto brake, press the hand brake lever with a screw driver inserted through the hole from rear side of the back plate.
