Sounds like you're having trouble with the power assist. Check vacuum lines to the brake booster if its a vacuum assist type. If its a hydraulic assist, check your fluid level, type of fluid (refer to your manual) and check for pinched/kinked hoses. Also, some systems come with a screen or filter...check to make sure its not plugged.

Try pulling on the emergency brake again it might still be on. Or you have a sticking brake caliper on one of the brake rotors this is most likely the problem. You can take it to any mechanic that doe's brakes and they can check it out but usually get two different shops opinions because some shops are lazy and will just tell you there is nothing wrong from experience. Most shops will check it out for free like Les Schwab.

Good Luck!

Burning smell brakes

Most people do not remove the rear rotors and inspect the Emergency Brake shoes. These often peel off the metal backing on the shoe and jam inside the interior Drum of the rotor. Some people will hear a rusty grinding noise after pulling away from a stop.

These brakes have the old "star-wheel" adjusters and may need to be adjusted more loosely to remove the rotor. Its a bad system in my opinion; the drum always rusts and corrodes and the Ebrake shoes are banana peel thin. With corrosion, the drum acts like a grinder and chews up the brake shoes. Some other configurations use a mechanical link on the caliper to make the service brakes act in an Emergency. It will override a hydraulic failure, but you still need good pads on the caliper.

Emergency brake handle on 2001 chevy colt won't hold, was replaced by RK DEALER and also the gas leaks, now the engine check light comes on

Your brake handle has two sets of gears that will lock against eachother. The button in the front of your handle acts as a release for the arm sode of those gears. Sounds like the button is jammed. Remove the cover fo rbetter access. Slide the cover off the arm Shoot some WD-40 inside the shaft where the button sits and push it in. If it doesn't push in, then it's probably jammed in. Maybe something is wedged inside. The check engine light is probably because of the gas leak. The computer senses the low pressure and prompts the caution. On a second notion, if you had the brake pads replaced on the rear wheels, it's possible that the cable needs to be re-adjusted for the new pads. The e-brake uses the rear pads for action. Good luck!

Have a crunching/grinding sound in the rt rear wheel. it breaks free but if i back up it like winds up and gets tight. its a 92 mr2 and this started after a 600ml trip.

this vehicle caliper system has the emergency brake made into the caliper and will stick and cause the piston for the caliper to stay engaged and brake to drag or lock up and will wear the pads out.also the brake caliper slides will get rusty and and stick or freeze up and cause this same problem and the pads to wear out and i have also seen but not to often a loose wheel bearing act the same way............hope this will help and good luck let me know what you find and if i can maybe help you any further..............

I replaced my rear brakes. Does the emergency brake automatically adjust itself?

Yes.....and no. Emergency brake should have been checked during brake pad replacement.
Most do adjust to new return to factory adjustment setting due to new pads .

The E brake lever should be applying braking to the wheels after three clicks are heard during application of the Emergency brake.

Lift rear of car and apply emergency brake to the third click. Now both rear wheels should drag equally but not be locked up.
If not, adjustment required.

However, late model cars need a scanner to pull back the pistons and install pads.

I just replaced the front brake pads on our 2006 Scion. I did NOT remove the whole assembly as the roters did not need replacing or turning. I removed the center roter assembly, but not the frame around...

To install:
  1. Install or connect the following:
    • Brake pads to the caliper mounting
    • Pin boots, sleeve boots and brake pads. Tighten the slide pins to 25 ft. lbs. (34 Nm).
    • Wheels
Did you tighten to only 25 ft.lbs.? It's not a lot so I hope you didn't smoke it down!

Heat coming from1997 geo tracker & front tires

sounds like you have a brake claiper piston not return causing the brake pads to drag, jack up both wheels and spin to see if you can feel or hear drag, give the wheel a hard spin and see if it stops right away or seems to spin freely, could be the drag of the pads on the rotor, or wheel bearings need repack or even as much as brake residual fluid pressure on calipers cuased by improper brake mc pushrod adjustment, if you have had any recent brake work like a MC replacement it could be that it was not properly adjusted as far as pedal free play... check those.. please let me know if this helps, rate my help...thanks

Sticking Brakes

You indicate your brakes were soft before and now they are hard to push. I would bet when you drive the vehicle for a few miles and then get out and feel the wheel it will be hot. It is obvious your brakes are dragging. Jack up all 4 wheels and see which wheel has the dragging brake. If you cannot turn the wheel by hand easily you have found the wheel. The question is why? The soft pedal and now hard pedal would tell me to first off replace all the fluid in the system and then bleed the brakes. If the problem does not go away I would then remove all 4 wheels and inspect each brake system on each wheel and replace the pads on all wheels. Inspect the rotor and have it turned or replaced if necessary. Look for corrosion, rocks, etc. Remove rust with a wire brush. Inspect the caliber slid pins and look at them carefully. If you see rust or pitting, replace the guide pin. If they look good then lubricate them with brake grease. If this does not solve the problem you may need to replace the master cylinder, which is what I would do at this point. You may also need to replace one or more of the rotors. Your truck may also have a proportioning valve that is not working properly. It is just a matter of eliminating one thing at a time. If you are not going to DIY I would seek out another mechanic as obviously the one you chose was not very good or he would have found the problem, which you know you have or your brakes would be working correctly.

Excessive dragging of new disc brakes

It's normal for new pads and rotors to have a "wear-in" period but only for say 50-100 miles of average driving... Disc brake DO get pretty hot, especially after prolonged or hard braking... (going down long hills or a lot of hard stops)... also front brakes actually supply 60% of stopping force... If they aren't to hot to touch the wheel or smoking you are probably OK... One thing to make sure of is that the pedal has "free play"... usually a fraction of an inch before the brake push rod actually pushes the master cylinder piston. Without this free play the brakes WILL drag all the time and wear prematurely... but unless you replaced the master cylinder or the locknut on the push rod adjuster has come loose it's rare to have that problem... The only other cause of this would be a malfunctioning ABS unit and you would feel a definite pulsation... Hope this helps...;-)

Brake problem on chevy cavlier

How is the brake fluid level in the master cylinder? If it's low, the brake light will come on. The right rear wheel and drum need to be removed to inspect the brakes and see what is going on. Your description sounds like there may be some brake hardware floating around inside the drum. Let me know what u find. Curt
