DRAINING - FILLING - BLEEDING BRAKE SYSTEM

1 - SPECIAL TOOLS

[1] Filler plug : Brake fluid reservoir (-).0810 .

Use a PEUGEOT approved automatic bleeding equipment .

2 - DRAIN AND REFILL

Remove the filter from the brake fluid reservoir (1) .

Drain the brake fluid reservoir using a clean syringe .

Refit the brake fluid reservoir filter .

3 - REFILLING

IMPERATIVE : use only clean fluid free from bubbles; avoid any introduction of impurities into the hydraulic system .

Use only approved and recommended hydraulic fluid(s) : DOT 4 .

Renew the brake fluid in the calipers by bleeding the circuit until clean fluid flows out .

WARNING : during the bleeding operation : keep the fluid topped up in the reservoir .

4 - RECOMMENDATION BEFORE BLEEDING A BRAKE CIRCUIT

Following work on the master cylinder or the abs unit bleed in sequence :

• the front left-hand wheel
• the front right-hand wheel
• the left hand rear wheel
• the right hand rear wheel

Following work on a caliper or a wheel cylinder, bleed in the following order :

• with the caliper or the wheel cylinder removed
• the front left-hand wheel
• the front right-hand wheel
• the left hand rear wheel
• the right hand rear wheel

NOTE : if the master cylinder is removed-refitted, it is advisable to complete the automatic bleed with a manual bleed .

ANTI-LOCK BRAKES

The hydraulic units are supplied pre-filled ; It is therefore possible to carry out :

• manual bleeding (at the pedal)
• automatic bleeding

If the bleeding of the circuit is not satisfactory, it is possible to bleed the ABS unit using TEP 92, DIAG 2000 diagnostic equipment, following the directions given by it .

It will be necessary to use the diagnostic equipment if the following conditions have occurred simultaneously :

• air in the circuit
• regulation unit active
• action on the brake pedal

ALL MODELS

5 - BLEEDING

IMPERATIVE : start the engine .

WARNING : follow the order of opening of the bleed screws .

5 - 1 - AUTOMATIC BLEEDING

Fit the equipment [1] on the brake fluid reservoir .

Connect the equipment [1] to one of the types of automatic bleeding equipment approved by PEUGEOT .

Bleed the circuit following the instructions for use of the equipment .

5 - 2 - MANUAL BLEEDING (AT THE PEDAL)

Two operators are necessary .

Connect a transparent pipe to the bleed screw .

Press the brake pedal slowly .

Open the bleed screw .

Hold the pedal fully down .

Close the bleed screw .

Allow the brake pedal to return naturally .

Repeat the operation until the brake fluid runs out clean and free from bubbles .

Proceed in the same way for the other wheels .
