My 2004 Toyota Corrolla GXi 1.8 front brakes appear to be in contact with the disc all the time. When I lift up the front off the floor and try turning the wheel with the Auto shift at N position, the wheels feel heavy to rotate and when I make a marking on the disc, it disappear after one round. Is this normal and if not what could be wrong.

take off the drums on both sides and do one at a time if you run into problems check the side your not working on to assist you.

Ive got a 92 Tercel. Had this same problem. Look around on the floorboard of your car. Look for a small rubber disc, or broken up pieces of the rubber disc.

If you see the pieces or whole hard rubber thing on the floor, then the rubber disc that goes at the point where the brakelight switch touches the back of the brake pedal has fallen off.

When that disc falls off the brakelight switch touches bare metal, and the switch is grounded which makes it stay on all the time.

Climb under the dash with a flashlight and look at the back of the brake pedal. Find the brakelight switch, look at the point where the switch contacts the pedal. See if the rubber disc is missing. If it
is missing find a small piece of rubber to superglue on the spot where the switch makes contact.

If the disc is there the brakelight switch is probably stuck. If its stuck you will see a gap between
the switch contact and the brake pedal. If its stuck get a replacement brakelight switch from an
auto parts store.

1. Put your car on a level spot for safety and start your car Sienna.
2. For left front rotor, turn your steering wheel to the left all the way and stop the engine. DO NOT put emergency brake on! Put stopping blocks on the passenger front front, rear right and rwear left for safety.
3. Half loosen all front left tire nuts and jack up the left front then loosen all nuts and take the wheel off.
4. Use a 3" G-clamp from Lowes, Home Depot or any store near you, press against brake cylinder so that brake fluid flows back to its reservoir
4. Remove one bolt on the caliper and the other bolt loosen and lift the caliper with the other bolt on and rest on a block. Do not take the rubber hose off nor attend to loosen any brake fluid pipes and nuts.
5. Remove brake pads and remove the nuts on the rotor, done.
If you need further assitance please let me know and if this assisted you please feel free to rate the solution accordingly. Thanks, Midwest-tek

To install:

1. Siphon a small amount of brake fluid from the reservoir. Press in the brake caliper piston with the proper tool.
2. Before installing the new pads, check the disc thickness and disc runout.
3. Install the pad support plates.
4. Install the anti-squeal shims to each pad.
   NOTE Apply disc brake grease to both sides of the inner anti-squeal shims.
   
5. Install the disc pads so the wear indicator plate is facing downward.
6. If removed, install the anti-squeal springs.
7. Carefully install the brake caliper so the boot is not wedged.
8. Install the wheel and tire assembly.
9. Check and adjust the fluid level. Apply the brake pedal several times.
10. Roadtest the vehicle for proper operation.

No they don't. If the feel smooth, then just change pads, if they are slightly scortched and feel slightly ruff, just have them turned.

you have air in your brake lines

Either you did not bleed the brakes properly or they need adjusted. (rear only) Front most likely are disks. If you put pads on the front and spread the caliper pistons, you should pump the brake pedal 10 or 15 times to move the pistons out. Some ABS systems are notoriously hard to bleed.

Normally this is caused by a problem with the brake light switch. If you don't take care of this soon you will have a dead battery, so try this. Look under the dash at the brake pedal. There will be a switch mounted on the backside of the pedal/arm that has a push button switch inside. Have someone stand behind the car and check to see if the brake lights go off when you pull the brake pedal away from the switch toward the driver's seat. If they do, then you need to turn the outer housing of the switch a little bit to make it pull away from the brake pedal when the pedal is in its resting position.

Sorry, I can't remember which way to tell you to turn it but a few turns should be all that it takes. If that doesn't work then you may need to replace the switch but they rarely fail.
