In the car interior, under the instrument panel, we pry two sound insulation holders with a screwdriver The connection of the main brake cylinder with the vacuum brake booster is sealed with a rubber ring. To prevent air from entering the hydraulic drive of the brake system, do not disconnect the brake tubes.Ĭarefully bending the brake tubes, remove the main brake cylinder from the pins of the vacuum booster and pull it aside. Unscrew the two nuts securing the main brake cylinder (article - Replacing the main cylinder brakes Renault Duster) Remove the check valve of the vacuum booster as described above We check the condition of the rubber sealing sleeve of the valve located in the opening of the vacuum amplifier housing. The air should pass in the direction from the amplifier to the receiver, but not in the opposite direction.īefore installing the valve, check the condition of the rubber seal of the valve tube tip The serviceability of the valve can be assessed by blowing into it (for example, with your mouth) in both directions. To do this, squeeze the two clamps of the valve tube tipĪnd disconnect the tube tip from the receiver fitting To assess the serviceability of the check valve, its tube must be disconnected from the fitting of the engine receiver. Having overcome the resistance of the clamps, we remove the check valve from the sealing sleeve of the vacuum brake booster housing. If this does not happen, then the vacuum amplifier or the check valve of the vacuum amplifier does not work, and the vacuum amplifier hose may also not be sealed. Holding the brake pedal in the pressed position, start the engine. When the engine is not running, we press the brake pedal five or six times on the brake pedal. If the force on the brake pedal has noticeably increased during braking, you need to check the amplifier on a stationary car. If the vacuum booster is faulty, the force on the brake pedal increases significantly Part# 1202- will lift the rear 1-1/4 inchesThe vacuum brake booster is replaced when it fails. Part# 1201- will lift the rear 7/8 of an inch Part# 1200- will lift the rear 5/8 of an inch To keep matters simple we have listed the lift for the three spacers we provide. Therefore if you want to raise the car 3/4 of an inch, use a 3/4 inch spacer.įord Models 1979-04 Mustangs rear follow a different formula. The formula for the rear GM models is one to one. Polyurethane is used for replacing the factory spring cushion.
All of the rear spacers that raise the vehicle are made out of aluminum. Rear spring spacers are available in polyurethane or aluminum. Using the formula one at the spring is two at the body, a 3/4-inch spacer is required to lift the front end up 1-1/2 inches.
#Rubber support rear spring boosters full
Your ride height will go up one full inch.Įxample 2: Lets say you want to raise the front of your GTO 1-1/2 inches because you cut to much off the spring.
#Rubber support rear spring boosters install
They install between the lower arm and spring. You would purchase two 1/2-inch spacers one for each side.
This applies to all Ford and GM models we deal with.Įxample 1: Lets say you want to raise your 1969 Camaro one-inch in the front. Selecting a coil spring spacer for the front end has a simple formula you must remember, one-inch at the spring equals two-inches at the body. The applications determine which is available. We offer three styles of spacers: Aluminum, Polyurethane, and Rubber.
Some are installed on top of the coil spring between it and the frame. For most applications, coil sprig spacers are installed under the coil spring between the coil and the lower control arm. 1968-74 Front Springs, Shocks, Sway Bar, Coiloverġ" Front Spacer - 1967-69 Camaro, Firebird/ 1968-74 Nova/ 1964-72 Chevelle, El Camino, GS, Skylark, Cutlass, 442, Lemans, GTO/ 1979-04 Mustang/ 1973-74 Omega/ 1969-72 Grand Prix/ 1971-74 Ventura- Sold Individually -part # 1106ġ" Front Coil Spring Spacer = 2" Lift (Aluminum)Ĭoil Spring Spacers are used to raise the vehicle up if its too low, leveling it, and for weight jacking if the car is being raced.
