Brake discs — inspection, removal and installation
1. Brake discs must not be ground and must be replaced if worn. Brake disc wear should not exceed 0.5 mm on both sides of the disc. Check the brake disc for runout. To do this, fix the dial micrometer in such a way that...

Rear wheel brake drums — removal and installation
1. Brake drums are removed and installed as described in chapter 17 when replacing rear wheel bearings. 2. Beforehand remove the device for installation of a normal backlash between a brake drum and pads. To do this,...

Rear brake pads — removal
1. After disassembling the brake drum, sketch the location of the individual components. This is especially important for return springs. 2. Jack up the rear of the vehicle and place it on axle stands. 3. Remove the...

Rear brake pads — installation
1. Move the setting lever of the leading brake shoe, and the lever of the hand brake of the driven brake shoe to new brake shoes, if they are changed: 2. Move the setting lever on the drive shoes as follows: A) Remove...

Brake drive booster
1. Do not repair the brake booster yourself, as this requires special tools. The failure of the booster does not entail a loss of braking, only the application of more force on the brake pedal is required to have the...

Vacuum Pump — Diesel
Vacuum pump (see illustration) serves to create a reduced pressure for the brake booster on models with a turbodiesel engine. Removing and installing the pump is not difficult. First you need to disconnect the hose...

Anti-lock braking system (ABS)
Second generation vehicles may be equipped with an anti-lock braking system. The system does not need frequent repairs. Diagram of the brake system with ABS and the location of its individual components are shown in...

Speed sensors and front wheel rims
The speed sensors are wired directly to the electronic module. The process of removing and installing the sensors is relatively simple, since after disconnecting the cable, all that remains is to remove them. The sensor...

Brake hoses
Brake hoses on early Espace models are structurally different as they do not use o-rings. The tightness of the connection is created by the cone-shaped end of the hose installed in the corresponding opening of the...
