Pressure Modulator Valve

Service and repair of the brake proportioning/combination valve can start after removing the brake pressure control valve. The six brake line fittings need removal before using plugs to seal the brake lines from fluid leakage. The service requires first removing the bolts which fasten the brake pressure control valve. To install the device perform the reverse order of steps from removal while completing a brake system bleeding procedure. Brake fluid handling requires attention since the mixture includes polyglycol ethers and polyglycols that produce irritation. Wear protective gear when working with brake fluid because contact with eyes requires immediate wash with water for 15 minutes followed by medical assistance when necessary while hand washing should also be thorough after use. An eye exposure requires immediate flushing with water for 15 minutes before medical help should be sought if symptoms do not improve. After ingestion of brake fluid drinkers should seek fast medical help after they drink water and vomit. The fluid poses a risk to painted surfaces and plastics so immediately clean affected areas by using water after any release occurs.

The brake proportioning/combination valve requires brake pressure control valve removal as a first step of service and repair work. The six brake line fittings need disconnecting while plugging the brake lines to stop fluid leakage. Proceed with the removal of bolts which attach the brake pressure control valve. After installation follow the approach of reversing the removal sequence while properly bleeding the brake system. Safety precautions should be taken when dealing with brake fluid because it includes polyglycol ethers along with polyglycols which can lead to skin irritation. Handle eye contact carefully by rinsing your hands completely after working with the fluid. Severe eye contact requires you to constantly wash with running water for 15 minutes followed by medical help for lasting irritation symptoms. Wash out the substance by drinking water followed by vomiting induction and urgent medical assistance. The hydraulic system contains brake fluid which needs caution because it damages painted surfaces and plastics thus any spills must get immediate water washing.
