usually either the calipers have dirt in them and need to be replaced or the rubber lines leading to them have collapsed inside and need to be replaced.. really kills the gas mileage uh!! chevy has had problems with rear discs on these vehicles,70%of braking is on the front,30% on the rear. therefore the pistons get little use and stick. there are stainless sliders the calipers move on,you need to clean and lubricate them,this should stop the brakes from dragging. I have a 1999 Blazer and my rear brakes were grinding so I replaced the pads and rotors but had the same sticking problem. They dont offer a rebuild kit for my calipers so I had to replace the calipers also.
Service brakes - replace Master cylinder Parking brake- either lubricate or replace cables ; I had a similar problem with my 1999 Chevy blazer, i ended up replacing the caliper and have had no problems since.
Directly above the brake pedal.
you can find the switch on the back of the brake pedal.
Sometimes a piece of carbon will get caught in the EGR Valve. If is is hard starting, idles rough, and the brakes are hard, check the EGR Valve, it probably has a piece of carbon stuck, keeping it open.
Your 1983 Chevy S10 Blazer might stall when the accelerator pedal is depressed because of a clogged or dirty fuel filter. Gas that is mixed with water or condensation from the tank can also cause this issue.
Under dash, drivers side, above e-brake pedal.
Clean the throttle body with a spray throttle body cleaner.
it takes 2 people,1 to pump the clutch pedal and the other to bleed it from underneath at the clutch slave cyl. but remember to keep the reservoir full at all time. it is kind of like bleeding the brakes on your car
Check your fluid level first. If it is low then your problem is a leak in the system. If the fluid level is OK then you probably have a bad master cylinder. To check the master cylinder pump on the brake pedal and hold the pedal down. Usually the pedal will slowly go to the floor. This means the master cylinder is not holding pressure. You should not take any chances with brakes!! Get them repaired at a qualified repair facility.
Follow the below steps to replace the Brake Light Switch on Chevy Blazer:1) Open the Chevy Blazer's driverdoor, and move the driver's seat as far back as it will go. Lean under the dashboard with the flashlight, and shine the light on the brake pedal arm to locate the brake pedal switch.2) Unhook the brake pedal wiring pigtail from the Chevy's brake pedal switch by hand. Unbolt the old brake pedal switch from the mounting bracket using the box wrench set.3) Remove the old brake pedal switch by hand. Insert the replacement brake pedal switch into the brake pedal bracket. Bolt the switch in place with the box wrench set.4) Plug the brake wiring pigtail into the replacement brake pedal switch by hand. Readjust the driver's seat, and close the door. Hope this helps.
If nothing is holding the pedal down then the brake light switch is at fault.
all cars with abs breaks do this!! but if you feel it in the pedal then you have bad front rotors!!
