Kia 591003E450 Booster & Master Cylinder Assembly

Brake inspections should happen every time wheels are removed or if a problem is suspected in addition to aftertime periods' elapse. Signals of faulty brake systems include the pulling of a vehicle to one side when any attempt to depress the pedal, squeaky sounds or rubbing noise on application and dragging brakes, extreme pedal travel distance, pulsations within pedals and even leakage of fluid for braking. First, loosen wheel lug nuts and then raise and secure the vehicle on jackstands before removing the wheels. The disc brakes can be visually inspected after removing the wheels hence each caliper with two pads; one outer and one inner pad. Lining material that falls below the specified thickness is replaced. In cases where doubts exist regarding pad thickness, or extra examination is necessary remove calipers clean pads using brake cleaner then take measurements of them. Replace any discs thinner than the specified minimum by measuring disc thickness using a micrometer only. Resurfacing may be required when discs have been marked by scoring, gouging, or burned spots. Inspect all brake lines and hoses for damage, wear, leaks etc., before putting back tires into place as well as solve these problems identified during inspection. Finally check your brake booster functionality as well as ensure its effectiveness during parking especially in Neutral state when you are at very steep hill so that it can inhibit rolling away while being parked thereon; thus requiring attention whenever this test fails on a given car model's parking system.

Begin by removing the brake master cylinder. If necessary, completely remove the brake lines that cross in front of it. Disconnect the vacuum hose from the brake booster, then remove the brake pedal return spring and the clevis pin retaining clip before pulling out the pin. Next, remove the four fasteners securing the brake booster to the firewall and slide the booster straight out.

The first step is to disconnect the cable from the negative terminal of the battery.
