Yes, my Dodge Caravan has brakes.
Brake cylinder repair is that wheel cylinder that holds the oil to keep your brakes running smooth on your back brakes. If you don't repair those you will mess up your rotors and your rims.
You need to "bleed" the brakes at each wheel. R
The Slave Cylinder and the Master Cylinder control totally different systems. The Slave has to do with the clutch, and the Master has to do with the brakes. They have nothing in common.
The best way to tell when you need brakes is by squeaking, when the brakes are rubbing against the metal, when your brake pedal goes all the way to the floor and when you are running out of break fluid.
If the rear wheel brakes are locking up on a vehicle they should be thoroughly checked. The master cylinder may need to be replaced on the car.
The issue here sounds like it's the master cylinder failing. It is not retaining pressure when the engine is running. The reason they feel fine when the engine is not running is because the failing master cylinder is not getting power, and in essence is being bypassed.
You need to bleed the brakes.
Either your emergency brake is hanging up or your wheel cylinder is leaking fluid and needs replaced if drum brakes and if disc brakes the caliper could be bad.
Check master cylinder for fluid level Check around all wheels for a fluid leak or bad wheel cylinder The reason you can pump brake up without engine running is that you are emptying the vacuum reservoir and no longer have power (vacuum) assist
I advise you to perform a careful examination of your car's brake system.
Air in system? Remove and bench bleed master cylinder Bleed lines and calipers
Jack car up. Pull tire . Set brakes adjust brakes to full out. Take cylinder out. Replace. Pump. Pump release. Untill no air. Readjust. So drum fits on. It done. 15 min..
I would suspect the Master Cylinder if defective. I had the same problem with my 1978. I replaced the combination valve and it solved the problem after bleeding.
A wheel cylinder describes "Drum Brakes" - Drum brakes have one cylinder with two diametrically opposed pistons.
Brakes are adjusted too tight. Brakes are misassembled. Brake hose is restricted, holdings the brake on.
Sounds like an airlock. You could try bleeding the brakes the old fashioned way but with the engine running so servo/power brake pressure shifts the airlock.
what size allen wrench do i need to change front brakes on a 2004 dodge grand caravan
The ECU for the ABS brakes is attached to the Master cylinder for the brakes.
Ruptured wheel cylinder--needs to be replaced Chances are brakes have been soaked with fluid and need to be replaced Good idea to replace both sides and bleed system
It's rare....because usually the master cylinder will allow pressure to bleed off. Not the other way around. But if you have replaced the calipers, this is the next thing I would check. I suppose it could be sticking.
The rubber hose that feeds the wheel cylinder has failed. It is restricted internally.
Did you replace the master. It might be by passing.
The best place to have your brakes replaced at would be Midas they would be able to replace both your brake shoes and even brake calibers if they need replaced.
