I - BLEEDING THE BRAKING SYSTEMS

Ensure that the level in the brake fluid reservoir is maintained during the bleed operations. Use brake fluid Lockheed 55, Nafic FN3, Stop HD 88 or Peugeot.

Engine stopped, without any servo effect.

Bleed each wheel cylinder, starting at the rear of the vehicle and then moving to the front Fig. I, bleeding first the upper cylinders (2) and finishing with the lower cylinders (1).

• Place a transparent tube, on each bleed screw, the other end of which is to be immersed in a clean container.
• Press down the brake pedal.
• Open the bleed screw.
• Hold the brake pedal fully depressed.
• Close the bleed screw.
• Slowly release the pedal against its stop.
• Repeat this operation until there are no more air bubbles in the brake fluid.
• Carry out these same operations on the other wheels.

Bleeding the brakes can be made easier by using equipment designed for this purpose (For example : ARC 50, PRESTOP)

II - ADJUSTING THE EMERGENCY BRAKE

• Press the brake pedal two or three times to operate the hydraulic system.
• Set the hand brake lever on the third notch of its travel.
• Tighten the nut (3), Fig. II, until the rear brakes start to engage.
• Check that when the hand brake lever is on the fifth notch of its travel, the rear wheels are locked.
• Tighten the lock nut.

III - ADJUSTING THE BRAKE SERVO THRUST ROD

Only on the conventional MASTER-VAC brake servo (1 compartment) fitted to naturally aspirated engines

The end of the thrust rod (5) should be recessed below the master cylinder mounting face, in the released position, by A = 0.3 to 0.5 mm. To obtain the recessed depth A = 0.3 to 0.5 mm, turn screw (4).
