Without knowing what kind of truck/car, I would believe that the best thing to do is take off the wheel and drum and have a look. Could be the springs, could be a brake fluid leak. Does the brake light come on? Do you have ABS? Could be a stuck parking brake cable. Is it drum or disc? If disc, could be a stuck piston in the caliper. Hope this helps.
With truck in neutral, and brake pedal pressed switch to 2wd it should click then go off.
on the brake pedal
replace brake hose they colaspe
Under the brake pedal is a brake light switch that when you press the pedal it hits it and makes your lights come on..sometimes when they get weak the pedal depresses them simply from the weight of the pedal and they stay on..Have a friend get inside the truck and pull UP on the brake pedal as you look at the lights..if the brake lights go off when they pull up on it..then it is that switch under the brake pedal
One reason that your truck might start to shake when the gas pedal is pressed is because the tires could need to be balanced. The problem could also be your shock absorbers, or struts. * It has less to do with the gas pedal as it has to do with parts affected by acceleration.
Check fuses for brake lights. If your brake lights aren't workings the truck will not release the parking pin as it needs the signal from the brake switch on the pedal.
Take your toe and pick UP on the brake pedal. The brake pedal may not be returning as it should.
it could be the brake light switch that usually contacts the break pedal when you depress the brake pedal. check that out first.
Where is the brake light switch for 2003 hd Chevy truck As far as I know, all brake switches are on the top of the brake pedal arm.
bad brake light switch
applying pressure to the brake pedal
On the firewall behind the brake pedal
It does not have a sensor, It has a switch and it is mounted just above the brake pedal.
Under the drivers seat area, under the truck on the frame rail, you will see the E-brake cable junction. Gently pry this apart and the brake will release. This will allow you to drive the vehicle until you can replace the release lever assembly. Remenber, your brake will not function until you replace the release lever. How about looking at the pedal mechanism just above the pedal and pulling on the release mechanism at the top of the toothed ratchet area where the cable would be if there was still a release cable.
check and see when your brake pedal is not pushed down if it is pushing the brake swith pin back in if so you need to replace the brake light swithch located behind the pedal
Check at the upper end of the brake pedal undeer dash area
It's attached to the brake pedal itself, near the pivot point at the top of the pedal.
disconnect it from your brake pedal lever.
The brake light switch relay for your 1997 Chevy truck is located beneath the drivers side dashboard. The brake light relay switch will be above the brake pedal.
If you break pedal is pulsing but is not soft or spongy, that sounds like the rotors on your truck are warped and they need to be turned. My suggestion would be take your truck to a local brake shop and have them take a look.
located at the upper end of the brake pedal under dash area
all brake light switches are connected to the brake pedal --- any car or truck or van
Typically, there's a hot switch attached to the pedal which closes the circuit to the brake lights (or to the CECU board in a truck which uses CAN BUS communication).
It depends which cable is broken. If the main cable is broken under the truck, the brakes should release on their own. If the brakes dont release, the cables are frozen from rust and need to be replaced. If the release cable from the handle to pedal assemdly is broken reach under the dash above the pedal and find the small release arm. Pull the arm toward you [ the rear of vehicle ] and the emergency brake pedal will release.
