How do you remove and install the brake booster on Honda Prelude?

To remove and install the brake booster, first disconnect the negative battery cable. Detach all electrical connectors from the master cylinder and remove the brake fluid, then use a flare nut wrench to disconnect the metal fluid lines. Next, remove the master cylinder from the brake booster and disconnect the vacuum hoses from the brake booster. From inside the passenger compartment, under the dash, remove the clevis and its pin from the brake pedal, followed by the removal of the booster mounting bolts. Take out the brake booster from the engine compartment. For installation, place the power brake booster back in the reverse order of removal, fill the master cylinder with Honda approved or equivalent DOT 3 or DOT 4 brake fluid, and properly bleed the master cylinder.

Honda Prelude Brake Booster

Honda Prelude Brake Booster plays an important function in improving the effectiveness of the car's brake through power booster which lessens the pressure the driver has to apply. The bulk of its action is predicated on vacuum operation, which makes use of the difference in pressure between the engine vacuum and the normal atmospheric pressure and uses the same to boost the force exerted on the brake pedal. With this system, there is free and efficient operation as far as braking is concerned. In case of Honda Prelude models, the Brake Boosters were often vacuum-operated, and while they have proved to be very reliable, they are also prone to failure. A typical vacuum booster can be obtained but boosters which feature dual diaphragms and those which come in different diameters differ depending on the performance requirement of the particular vehicle. Variety of Brake Booster can apparently affect the driving pleasure setting-much more so if the model comes with disc or drum brake systems-the degree of boost can apparently be adjusted to improve control and response.
