Faults of brake proportioning valve
mechanical damage;
metal corrosion;
faulty pistons;
drive failure.
Symptoms of brake proportioning valve failure
skid or wobble of the vehicle during braking;
increase in the rigidity of the brake pedal;
incomplete locking of the rear wheels when the brake pedal is fully depressed;
increase of the braking distance;
stains of oil or brake fluid on the rubber boot;
air in the rear circuit;
warning readings.
Causes of brake proportioning valve faults
longer use of spare parts than the specified service life;
low amount of brake fluid;
oxidation of the pistons;
ingress of air into the circuit;
weakening or deformation of the actuator arm;
damage to the boot;
ingress of dirt or foreign objects.
Diagnostics
Faults of brake proportioning valve are very difficult to identify on your own because its symptoms are similar to the entire brake system malfunctions. you should diagnose the item every time you change the brake fluid - every 1-1.5 years. The average service life of the valve is about 2 years.
Replacement of the brake proportioning valve
Repair of the brake proportioning valve is not performed. At fault only part replacement is required. When serious errors and failures in the system occur, you can temporarily disconnect the valve. To do so, directly connect the master cylinder to the rear circuit.
To replace the valve, unscrew the mounting of two main and two exhaust pipes of the part. The part must be replaced only at a service station.
