Tahoe 98 brakes to stiff just replaced all brakes

for one, a "cheap" tune up is never recommended for any vehicle. always use quality parts and when doing it, always replace the plugs, wires, and depending on model, distributor cap and rotor, those all are not expensive and save you down the road from disaster. SSBC or BAER are good systems for doing a drum to disc conversion, they have Great instructions and brackets to make the switch over less painful then it used to be. hope this makes it a little easier for you

I think this is just a switch located at base of steering column which is actuated by the brake pedal arm.

Your brake lights are also connected to your hazards.

If your hazard button does not activate 4 way flasher, culprit is your stalker.

Just changed mine on 98 Burb......

Takes about an hour do change.

I've got the same problem on 98 GMC Sierra.

I'm an electrical engineer, I checked the electrical diagrams and verified that there is no problem in the rear lamp assembly or wiring. With the light assembly unplugged, I can actually watch the blinker and brake signals operate with a voltmeter. The Tail light works OK.

It simply won't provide enough current to light the bulbs.

I'm afraid that it's melted one of a pair of normally closed contacts inside the blinker switch that feed the brake and turn separately on each side.

ACTUATOR MOTOR ON 98 TAHOE
SEAT BELT RETRACTOR REPLACE OR SOMETHING DEBRIS STUCK IN IT

Replace the brake flex lines.

if your brakes are too stiff to push pedal then the brake booster is bad

you have a vacuum leak from the brake booster probably down by the pedal if you can hear it inside the truck.

There is a clip that gets worn on the brake pedal that holds the switch tight to one side. It must be put on correctly or else the brake lights will come on for a split second and then go out when you push the brake pedal down further.

98 Z71 Chevy rear end will work on this. You may need to get a kit to install disc
