Usually called a coaster brake. It's built into the rear hub and can't be added later - unless you replace the whole hub.

How do you repair a soft brake pedal on a 1990 silverado after replacing front padsrear shoes and wheel cylinders?
The 'soft' brake pedal is likely a result of air entering the braking hydraulic system when the wheel cylinders were removed and replaced. Basically anytime a brake line is removed it is possible for air to enter the system. You will need to 'bleed' the air out of the braking system by having some other person pump up the brakes and hold pressure on the brake pedal while another person opens the bleed valve on the back side of the wheel cylinder. When the valve is opened fluid (and hopefilly air) will escape through the bleed valve and the pedal will go to the floor. The valve must be closed while the person in the vehicle holds the pedal down. Top off the brake fluid reservoir and proceed to the next wheel and repeat the procedure for all wheels. Ultimately, the system will only contain fluid (and no air) and the pedal will be hard.
What does the vacuum pump on back of alternator on1986 izusu turbo diesel do?
my 1997 hino only has braking power some times and the brake pedal is allways the same
The back brakes pads calare not going in how can you get them to go in on a 2000 bettle vw?
If you are having trouble with the thickness of the pads, you may have forgotten to press the piston(s) back into the caliper. You'll need a piston press tool to do this correctly. Do this slowly as not to aerate the fluid in the lines. This will cause a spongy brake pedal and will likely compromise the performance of the braking system.
Do trailer brakes automatically lock when the air lines have been disconnected?
Air pressure within the air braking system of a tractor-trailer (or large truck) is what prevents the brakes from being applied. The pressure of the air pushes back a large spring at each wheel. The large spring will apply the brakes when there is no pressure in the system. When the driver steps on the brake pedal, air is released out of the system and the brakes are applied. When the driver's foot comes off the brake pedal, air is quickly pumped back into the system and the brakes are released. Disconnecting the air line has the same effect on the trailer's brakes. Air is released from the system, and the brakes are applied. It is not the brakes themselves that lock. Application of the brakes causes the wheels to lock.
Abs indicator light came on your dodge van 3500 mechanic replaced rear brakes and oil seals light went out had good pedal 20 miles light back on brakes work but soft pedal?
Soft pedal indicates air in system. Bleed the system of all air.
Why would the rear brakes of a 1996 Chevy Corsica engage very hard with the slightest touch of the brake pedal?
The rear brakes are called a dual servo brake system... it uses one shoe to activate the other in a braking situation. When the rear brakes are over adjusted the slightest touch of the brake pedal will cause them to engage. what is actually happening is your rear brakes are engaging before the fronts even get close. You need to either back off the adjusters yourself if you know how or take it to a garage and have them back them off.
What can cause braking to be bumpy?
If your brake pedal pulses it could mean that the rotor is warped or that the brake pads are worn to the point where the metal back is cutting into the rotor. You should not drive the car any further than to the nearest garage to have it repaired.
How do you fix leaking clutch fluid at the pedal?
The fluid is leaking from the master cylinder and running back towad the pedal. Replace the master cylinderanswerchange master cylinder and slave properly then bleed the system properly.
Why is free play necessary at the master cylinder?
Brake pedal free play is critical because it assures that after braking the master cylinder piston comes back far enough that is does not block the transfer port to the reservoir, allowing that pressure that was built up when you braked to return to the reservoir and relax the system. Around 5-7 mm of free play is needed.
What does braking someones back mean?
It means that you have broken a bone or a part in someones back.
Whats the shift pattern for an ultra classic?
* Front pedal down = 1. Back pedal down = 2,3,4,5. Neutral between 1 and 2. * Front pedal, no further movement, 1st. Back pedal, no further movement, 5th.
What is BAS in a car?
The Brake Assist System (BAS), an electronic system by Mercedes-Benz, interprets the braking behavior of the driver and initiates the full braking effect when it identifies an emergency situation. This reduces the braking distance substantially. Here is the engineering foundation for BAS: Conventional braking systems usually use engine vacuum to increase braking capability. Instead of relying solely on vacuum power to provide effective brakes, an electric pump pressurizes brake fluid to provide power assist for BAS and the necessary brake force for 4ETS.The pressurized brake fluid is stored at about. 180 bar (2600 psi!) in a reservoir known as the accumulator. From the accumulator the high pressure brake fluid is supplied to the hydraulic operating cylinder in the master cylinder assembly. Commands to utilize the pressurized fluid comes from either 4ETS or BAS. When the brakes are applied and BAS deems it necessary, a lever connected to the brake pedal releases varying amounts of the high pressure fluid to assist in stopping the car.Here is what BAS does for you: Most drivers, under normal braking conditions as well as under emergency conditions, start out with little brake pressure and whenever necessary they will increase their pedal effort. In an emergency this behavior leads many times to a crash since the car could not be stopped in time. Those situations require maximum pedal pressure from the beginning - if necessary the effort can be reduced later in the process. With other words most drivers do not use the ability of the brakes to their advantage - BAS automatically corrects that. The system recognizes emergency situations within milli seconds and releases pressurized brake fluid into the system as soon as the driver touches the brake pedal. As soon as the driver releases the brake pedal, BAS kicks back into a standby mode. BAS creates a much higher stopping force for emergencies than most drivers are ever able to generate. By doing so BAS helps to prevent accidents
