The proportioning valve is mounted between the brems line master cylinder and the rear wheels. It's designed to adjust the pressure between the front and rear brakes, depending on how hard you're stopping. The shorter the stopping distance, the more of the vehicle's weight is transferred to the front hjul. This will cause the rear wheels to lift and the front wheels to "dive" down. The valve controls how much pressure is applied to each of the braking system's axle sets. In the case of the short stop, it will direct more pressure to the front wheels and less pressure on the rear wheels. The proportioning valve is the key component to a safe, reliable braking system . The instructions below will guide you as how to install a proportioning valve.
Check your owner's manual and familiarize yourself with your car's braking system
Finn hovedsylinderen. Du vil se to bremseslanger som kommer ut av hovedsylinderen. Proporsjonsventilen er på linjen nærmest motoren.
Fjern den gamle ventilen ved å kutte den av fra begge sider av ledningen. Bruk en rørkutter for dette trinnet. Skyv den nye ventilen på plass, fest den med en rørgjengetetning. Ventilen bør plasseres i nærheten av -låsefri bremsesystem (ABS) kontrollenhet.
Make sure the valve isn't touching or rubbing against any brake lines, as this will cause wear and tear, and can endanger the passengers in the car.
Når den nye ventilen er på plass, luft bremsene for å fjerne eventuell luft som er fanget i ledningen.
Tilsett så mye ny bremsevæske som er nødvendig for å nå riktig nivå.
Take the car for a test drive and make sure the brakes are working properly Gjør det selv.
