Diagram of 1998 Chevy Lumina Rear Brake Assembly

SOURCE: 1998 chevy lumina brake lights intermittent.

This is a classic example of turn signal switch failure. On GM vehicles with a multi-function turn signal switch and combination stop/turn/tail lights (all rear lights are behind red colored lenses except for back-up lights) The brake light power is routed through the turn signal switch. This makes it possible for the right rear light to function as a stop light while the left rear turn signal flashes, and vice-versa. When the contacts fail to remain constant the brake lights, and turn signals can become intermittent. The proof that the brake light switch is functioning correctly is that the high center (cyclops) brake light functions properly. Wiring integrity is verified if you can prove that turn signals operate, but that can still be intermittent with this complaint, BUT if you use your hazard switch to turn on all the signals at once, you can verify wiring integrity. This is because the turn signal, and the brake light use the same circuit, and bulb filament in the rear lighting assembly. If any Hazard lights fail to function, check bulbs first, then retest. If all Hazrd light flash correctly and reliably, bulbs, sockets, and wiring have proven integrity, and the turn signal switch is the remaining component in the system which needs to be tested. Unfortunately, this switch requires disassembly of the steering column for service, testing or replacement. If you have never disassembled, and successfully reassembled a GM tilt steering column, I would reccommend professional assistance.

there should be several springs. first there are (2) real short springs that hold the shoes to the dust cover/back plate. they go in the center of each shoe. then there is a short spring that goes at the bottom where the adjuster is located. there should be a hole in each shoe. finally there is a long spring that goes at the top where your brake cylinder is and this is what gets attched last after your emergancy brake levers are placed between the shoes .

Here is the diagram,It is always a good idea to only disaasemble one side so you can use the other side as a reference,I also reccomend using a set od brake pliers,they will the disassembly and reassembly much easier.

I've had this problem. I tested everything and in my situation it was the four way switch that controls the blinker/high low beams/cruise control. If you depress the peddle, push the blinker lever forward or backward slightly you may see the brake lights come on. you would then know this switch is worn.
