Adjustments

Disc brakes require no adjustments. The rear drum brakes on all models except LeCar are self-adjusting and require only an initial adjustment when new shoes are installed. The LeCar rear brakes require periodic adjustment.

Fig. Fig. 1 Adjusting the LeCar's rear brakes-the front adjusting lug (C) is rotated forward while the rear adjusting lug (T) is rotated rearward

Always start with the leading shoe. The brakes are adjusted by means of eccentric cams which bear against the shoes. These cams are turned by rotating the lugs on the back of the backing plate.

  1. Turn each lug toward the outside of the drum until the shoe contacts the drum.
  2.  
  3. With the shoe against the drum, the drum should not be hand-turnable.
  4.  
  5. Back off on the shoe until the drum can just be turned by hand.
  6.  
  7. Perform this for each shoe.

Fig. Fig. 2 Rear brake adjustment on the R-12, R-15, R-17 and Gordini-(E) is the lever peg

This adjustment is for new brake shoes. No periodic adjustments are necessary.

  1. Remove the plug in the backing plate.
  2.  
  3. Insert a long, thin screwdriver or punch through the hole and push the handbrake operating lever in to free its peg from the brake shoe. The shoe is drilled to permit passage of the screwdriver. Once the peg is free, push the lever to the rear.

Fig. Fig. 3 Fuego and R-18 rear brake adjustment-(H) is the gap measurement point

This adjustment is for new brake shoes. No periodic adjustments are necessary.

  1. Raise and support the rear of the car on jackstands.
  2.  
  3. Remove the wheels.
  4.  
  5. Remove the brake drums.
  6.  
  7. Look at the front shoe. The brake shoe cross link has a hooked end which enters the shoe webbing. Measure the gap (H in the illustration) between the inner face of the hooked end and the shoe webbing. The gap should be 1mm (0.039 in.). This measurement should be taken with all tension released from the parking brake. If this dimension is not correct, it will be necessary to replace cross link tension spring as well as the two brake shoe hold-down springs.

  9. Install the brake drum and adjust the bearing end-play.
  10.  
  11. Press down on the brake pedal several times.
