Your brake light switch is adjusted in all the way and is pressing on the brake pedal. This causes the brake to be slightly applied. As you drive the vehicle the brake fluid heats up and expands, the brakes will apply more and more until you see the smoke. Bottom line: your brakes are always applied at the master cylinder because something(usually the brake light switch) is out of adjustment.

What is the part called that the brake lines hook into?


Hi,
Under the hood is the Master Cylinder. It contains brake fluid, which when you depress the brake pedal, acts as hydraulic fluid to flow through high pressure tubing called brake lines, from the Master Cylinder to the Wheel Cylinder (drum brakes) or Brake Piston Caliper (disc brakes). As you depress the pedal further hydraulic pressure expands the wheel cylinder which presses outward, 2 brake shoes inside a metal "drum" (drum brakes) or clamp the brake piston calipers together squeezing a disc-like rotor (disc brakes) thus stopping the vehicle.

Rear wheels lock up on my dodge dakota


What year Dakota? Drum Brakes?

Lock up when?

If you use the parking brake,then the cables
have to be replaced because of rust.

With proper brake maintenance once a year, there is no
reason to say they lock up while driving

Brake shoes on 1987 f250 460 1987 2 wheel drive how to replace


Lift the front of your Ford F-250 off of the ground using a jack and jack stands. Remove the wheels from the Ford with a lug nut wrench to prepare the truck for servicing. 2 Open the hood on the engine compartment and take the lid off of the master cylinder that bolts to the brake assister on the driver's side firewall.3 Remove the hex-head bolts on the back of the brake caliper with a socket. With the bolts removed, pull the caliper off of the Ford's brake rotor.4 Pull the old brake pads out of the caliper and discard them. Squeeze the brake piston back into the backside brake caliper with pliers, and then insert the new pads into the brake caliper.5 Pull the rotor cap cover off the middle of the rotor with a screwdriver and use a socket to remove the nut located behind the cover.6 Pull the rotor off of the wheel spindle.7 Remove the old wheel bearings from the brake rotor and insert them into the new rotor. If the old wheel bearings are worn, replace them with new bearings.8 Slide the new rotor onto the wheel spindle and secure it using a bolt and socket. After you tighten the bolt, press the cover back onto the rotor.9 Place the caliper on the rotor and secure it with a socket and hex-head bolts. 10 Duplicate the process on the passenger side of the F-250. 11 Close the master cylinder after putting the wheels back on the Ford and lowering it to the ground. Press on the brake pedal to seat the pads against the rotor
Replace the F-250's Rear Brakes 1 lift the rear of the Ford F-250 off the ground with a jack and jack stands. Remove the wheels from the Ford with a lug nut wrench.2 Place a strip of paint on the back of the brake drum and rear brake drum cover so you can position the brake drum orrectly when you put it back on. If you plan to install new brake drums on your Ford F-250, skip this step. 3 Place the brake drum puller on the brake drum and pull the drum from the wheel hub. The method for attaching the brake drum puller depends on the brake drum puller that you use. 4 Remove the springs that attach the brake shoes to the wheel hub by pulling them off with pliers.5 Lift the old brake shoes off of the wheel hub and place the new brake shoes on the wheel hub. Secure the new shoes with the springs.6 Pound the brake drum onto the axle hub with a rubber mallet.7 Duplicate the process on the passenger side of the Ford.8 Put the wheels back on the F-250, lower it to the ground and, then press on the brake pedal to seat the shoes against the brake drum.

We are trying replace rear brake pads on 2006 Montana & there not enough clearance for new brake pads to fit on drum


pads go over a rotor, you can buy a tool to spread the pads meaning pushing the caliper piston back. if the rotor is pitted or has a lip around the outside it needs to be refaced which is done at a machine shop. i myself use a big old C clamp instead of buying a tool. be careful not to put sideways pressure on the piston or you will be buying a new caliper. i take the cap off the master cylinder when i am pushing fluid out of the caliper.

shoes go inside a drum, you get the drum turned at a machine shop, and you move the adjuster wheel down to the minimum and slowly back it out to where the drum just does not contact the shoes when put on. the shoes will settle in correctly when you push on the brake pedal so you may have to do this adjustment a few times. in the olden days the adjuster was accessible from the inside through a slot in the backing plate and you used a special adjuster or a bent screwdriver to adjust the shoes out.

good luck

How to remove brake rotors on a 1996 ford explorer


How to replace the rear brake pads on a 1995 through 2001 Ford Explorer The system utilizes a drum-in-hat type rear brake rotor. The integral drum allows the use of a drum-and-shoe type parking brake system. All other components are similar to their front disc brake components Remove the two bolts on either side of the brake hose with the rubber boots. Do not remove the four bolts where the axle ties in. The two bolts to be removed require a 10mm socket/wrench. Loosen the pads from the caliper Rotor Removal In order to take the rotors off (replace with new or have them machined), it is best to loosen the emergency brake shoes. To do this, behind the rotors, in the back there is a rubber plug, remove that and you can use a screw driver to engage the teeth of the adjusting screw, turn it clockwise to loosen, usually 10-20 teeth. Usually this means turn it downward. After this, it may still be difficult to get the rotors off without tapping them. Use a rubber mallet and hit them from behind. Before really whacking the rotor, make sure you have loosened the adjusting screw enough. It may take heavy swings of the rubber hammer to do this. It will eventually break loose. Parking Brake You might want to check the parking brake while you are here. To remove:
  • Remove the rear disc brake rotor.
  • Remove the outboard return spring.
  • Remove the adjusting screw spring.
  • Remove the rear brake shoe hold-down spring and pin.
  • Remove the brake shoe adjusting screw and nut.
  • Remove the front brake shoe hold-down spring and pin.
  • Remove both parking brake shoes and the inboard return spring.
  • Check the parking brake lever for excessive wear and replace as necessary.
To install:
  • Position the front parking brake shoe to the backing plate and install the hold-down pin and spring.
  • Install the rear parking brake shoe with the inboard return spring.
  • Position the brake shoe adjuster screw and nut on the shoes and install the rear shoe hold-down pin and spring.
  • Install the brake shoe adjuster spring.
  • Install the outboard return spring.
  • Adjust the parking brake shoes and install the rotor, caliper and wheel.
  • Lower the vehicle and tighten the wheel lug nuts to 100 ft. lbs. (135 Nm).
ADJUSTMENT
  • Measure the inside of the drum portion of the rear brake rotor
  • Remove the rear disc brake rotor.
  • Using Brake Adjustment Gauge D81L-1103-A or equivalent, measure the inside diameter of the drum portion of the rear disc brake rotor.
  • Subtract 0.020 in. (0.508mm) from the first measurement, adjust the brake shoes to that size
  • Adjust the parking brake adjuster screw until the outside diameter of the parking brake shoes measures 0.020 in. (0.508mm) less than the drum measurement.
  • Install the rear disc brake rotor.
Reassembly Reassembly is easy. Put new or machined rotors back on by sliding them over the lugs (they should slide on easily.) Loosen bleeder valve (having a catch bottle handy is good). Push calipers in slowly (using a c-clamp or large channel lock pliers), close bleeder valve. Put on pads. Lubricate metal clips with small amount of anti-seize. Re-adjust the emergency brake by turning the opposite direction from loosening. Refill the brake master cylinder
