TWO WHEELER BRAKE AND CLUTCH PLAY ADJUSTMENT
To adjustment of brake and clutch as per specification.
TOOLS REQUIRED :
Due to the continuous use of the brakes, wear take place of the brake lining, linkage etc., which necessitate periodic inspection of the braking system and to make suitable adjustment. The brake adjustments can be broadly divided in to two types, viz, the minor and major adjustments.
Minor adjustment mainly includes the adjustment of brake shoes to compensate lining wear and is done without removing the wheels. A major adjustment on the other hand, has to be done after installation of new shoes or relining the old shoes. If the following conditions are not found, the minor adjustment is usually sufficient;
- Worn out or out of the round brake drum
- Brake lining soaked in oil
- Brake lining worn upto the rivet heads
To perform minor adjustment, on turning the adjustment nut the cam is also turned. This cam is fitted on the brake shoe and the adjusting nut is provided on the back plate. Turning this nut with spanner in the clockwise direction causes the shoes move closer to the brake drum.
To perform major adjustment, remove all brake drums and inspect linings and drums. If the drums are worn out, turn them in case the damage is with in limits or else replace them. In case of linings having reached upto within 1mm of rivet heads, remove the same and reinstall the new ones.
Clutch assembly is fitted between engine and gearbox. The purpose of the clutch assembly to transmit power of the engine to the rest of the transmission system, by disconnecting & connecting the power is required.
CLUTCH ADJUSTMENT :
The only adjustment required in a clutch is of the free lever play, which is necessitated on account of wear of the friction lining due to continuous use or with the wear of the throw out bearing carbon ring due to the habit of the driver to press his hand always on the clutch lever. The wear of the friction lining decreases the free lever play. An adjustment nut is provided at the lower end of the clutch lever. To slacken the lock nut first, make the desired adjustment with the adjusting nut and retighten the lock nut.
Thus the adjustment of brake and clutch as per specification is performed.
