Dual pressure regulator
1. Brake pipe; 2. Bolt; 3. Pressure regulator
1. Double pressure regulator is installed on the thermal insulation shield. A precise check requires specialized testing equipment, but you can suspect that the adjuster is faulty if, under heavy braking, the rear wheels lock up before the front wheels, or if the rear brakes do not work at all.
2. To remove the regulator, first clean it, then unscrew the hydraulic connections from it. Prepare a rag to collect any leaked hydraulic fluid. Be careful not to let the liquid come into contact with the painted parts.
