The service brake system is hydraulically actuated. The system uses a vacuum brake booster. The brake system consists of two circuits. The front brakes are disc brakes, and the rear brakes are drum brakes. The handbrake is mechanically actuated and actuates the rear brakes.
Front brakes
The front brakes are disc brakes. They use full discs and single-piston floating calipers.
| Brake disc outer diameter | 240 mm |
| Disc thickness: | |
| - nominal | 12.65 mm |
| - minimum acceptable | 11.3 mm |
| Maximum disc runout | 0.15 mm |
| Caliper cylinder diameter | 54.0 mm |
| Brake pad type | Girling D 600 FF |
| Brake pad sizes | 38 x 111 mm |
| Thickness of overlays (without base plate): | |
| - nominal | 12.5 mm |
| - minimum acceptable | about 1.5 mm |
Rear brakes
The rear brakes are drum brakes and are equipped with an automatic brake shoe clearance adjustment mechanism.

| – minimum acceptable: | 1 mm |
| Type of pads | N/ F 360 IF.FF |
Master brake cylinder
In the cavity of the main cylinder there are two pistons located in series, each of which controls its own circuit.
Vacuum brake booster
The brake booster operates on the master cylinder and contains a single diaphragm.
Pressure regulator
The pressure regulator is installed on the rear brake line and limits the braking force of the rear wheels.
