Note: Brake calipers are supplied in a repair kit with a cylinder filled with brake fluid.
When replacing brake pads or a brake disc, be sure to replace them on both sides of the vehicle. Place the vehicle on a lift.
Install a pressure device on the brake pedal to reduce the amount of brake fluid leaking out.
Unlock the steering wheel. Remove the front wheels.
Disconnect the brake hose from the brake caliper.
Unscrew the two mounting bolts (1) of the guide pins.
Remove the caliper.
Remove the brake pads.
Check the condition of the brake system components (replace damaged parts).

Clean the guides and the calipers themselves.
Move the piston using the tool (Fre. 1190-01) until it stops at the bottom of the cylinder.
Install new brake pads, starting with the inner pad.
Install:
- support;
- guide pin mounting bolts.
Tighten to the specified torque:
- guide pin mounting bolts (32 Nm);
- brake hose (17 Nm).
Caution: Securely fasten the brake hose and wheel speed sensor wires if they were disconnected.
Do not twist the brake hose. Install the wheels.
Tighten the brake bleed screw to the specified torque (6.5 Nm).
If the brake fluid reservoir was not completely drained during the work, bleed air from part of the brake system hydraulic circuit. Otherwise, bleed air from the entire hydraulic circuit.
Check the brake fluid level.
Brake caliper repair
Push the piston out of the cylinder by forcing a stream of compressed air through the air inlet, having previously inserted a wooden lining between the bracket and the piston to avoid damage to the piston. Any damage to the piston skirt makes it unsuitable for further use. Remove the protective cap.
Using a flexible plate with a rounded edge (for example, a feeler gauge) remove the rectangular sealing ring from the cylinder groove.
Note: If there are scratches on the wheel cylinder mirror, the caliper assembly must be replaced.
Clean the parts with denatured alcohol.
Install:
- new rectangular section sealing ring in the cylinder groove;
- piston (after lubricating it with grease from the repair kit tube) using a device (Fre. 1190-01);
- protective cap.
