Were and how do you change a brake light switch on a Daewoo Leganza 2001
1. Remove the brake hose to caliper bolt from the brake caliper. 2. Remove the brake hose from the brake caliper. 3. Remove and discard the 2 copper brake hose gaskets. These gaskets may be stuck to the brake caliper and/or the brake hose end. 4. Cap or plug the opening in the brake caliper and the brake hose to prevent fluid loss and contamination. 5. Remove the 2 brake caliper pin bolts. Remove the park brake cable from the caliper. 6. Remove the brake caliper from the brake caliper bracket.
There should be no need to bleed the brakes after replacing the rear (or front) brake pads. Make sure you place a rag around the top of the fluid reservoir to catch any excess as you press the pistons back into the caliper body though. If the brake pedal has gone spongy after pad replacement this suggests that the piston seals have failed or the caliper cylinder facess have corroded. On mine the bleed nipples are on the caliper body.
