BMW E36 brake caliper sticking and brake warning lights
316i
Why does the E36 brake caliper stick?
The caliper pistons seize, so pieces that have come loose rub the disc. There can also be sand in between. The part number of the rear caliper seal kit is 34211159171; the kit is per side, so two are needed for both sides. The ATE kit is a good alternative.
The brake wear sensor light is on. What is wrong?
Wear sensors are single-use, and the light stays on until the sensor is replaced. Too low a brake fluid level can turn on the same light, so also check the fluid level.
Why do the handbrake indicator light and exclamation mark come on at start-up?
The cause can be the contact at the base of the handbrake lever, which is broken or knocked out of place. It is reached by removing the lever's protective boot on the driver's side.
