If the brakes release after the front bleeder is open the fault is at the master cylinder, Adjust the brake rod to master cylinder piston so there is at least 1/16 inch free play, the master cylinder bucket is covering the oil return port.

2011 dodge caravan front brakes extremely hot


Make sure that your rubber hoses that go to the calipers are in good shape and haven collapsed internally.

Jun 09, 2015 | 2011 Dodge Grand Caravan

1 Answer

01 explorer just did a pad swap and the front two calipers are dragging.


First, try bleeding the longest brakeline first, then next longest, and so on.

You can try troubleshooting several ways. Here are some possibilities: Front rubber brake hoses collapsed internally.(There is 1 way pressure to calipers, Gravity return) Master cylinder, sticking Calipers, ABS valving.

A diligent mechanic would attach a pressure gauge on the Brakelines to isolate the problem. If the pressure did not return to Zero after the Brake pedal was released, the individual component can be identified and replaced.

The cost to run the tests is compared to Labor to replace the bad part. With testing you only buy the part you need. You pay a third party to replace the single bad part versus guesstimates and doing it yourself.

Front end rubber brake hoses, cheapest, then Master cylinder or single Caliper. But if replacing both Calipers, they combine to cost more than a Master cylinder. ABS unit $$$

Labor versus parts. Some of the parts may be needed with guesstimates so difference really is buying something you don't need YET. You can look at it a preventative maintenence.

Brake specialty shops. Can do testing. Some offer lifetime Warranties on parts. Quick You have already installed pads. Repair place may not guaranty without replacing your new pads.

I hope my solution is helpful, please rate.

Driver side front brake keeps locking up we have changed the Caliper rotor and pads 3 times now, what do I look at next


Your MOST LIKELY problem is a defective brake hose. The hoses are made up of several layers. There is a rubber outer shell and a steel or kevlar reinforcement and a silicone-based inner lining that will resist the brake fluid and prevent the brake fluid from eating the other layers. What happens is that the inner lining tears loose inside and acts like a "heart valve" The liner will expand when dthe pedal is applied and allow fluid to be pushed into the caliper under pressure. However, when the brake pedal is released, the hose collapses and prevents the fluid from returning to the master cylinder.

The way to diagnose this condition is like this:

Raise and support the vehicle and remove the tire on the side that keeps destroying brake pads.
start the engine and press ******* the brake pedal and then release the brake pedal.
Turn the engine off and check to see if the caliper has the wheel locked up.
If it does, then open the bleeder screw on the caliper. The fluid should squirt out under pressure and the caliper will release the wheel. If it does, replace the hose.

Hello: You nare going to have to replace/rebuild front calipers, replace Both rubber hoses that go fron the frame to the calipers. You may have to replace the rubber hoses in the rear and the rear wheel cylinders. Contaminated brake fluid creates a expensive and long repair.

Front brakes dragging


First of all you will need to raise the wheels off the ground. Check both sides to see if they are both holding. Here is a list of what can cause the hanging in order of probablility;

1) Caliper or Caliper hose. (If the caliper is not free it won't release the pressure from the pad. Always replace the hose with the caliper because the hose may look good, but can collapse internally holding the pressure.

2) Master cylinder. Not likely but possible.

3) ABS is engaging. This can be caused by a short, it is rare, but it does happen. The short is telling the system that the wheel needs to be applied.

Caliper won't release on right front brake--everything is new, replaced because of that problem but no fix


Check the left rear brake for sticking on also, if it is then you have a master cylinder problem. replace brake master cylinder but check the adjustment of the brake light switch first. the switch is above the brake pedal, make sure it is not holding the pedal partially on.

Rear brakes drag hard pedal


easy fix NOT!!!!!!! at least that is what i thought. it is the rubber hose going to your rear axle to you're frame channel mine was so clogged that we could not get 125 psi. through it the main problem is that lines are probably rusted .i ended up replacing lines from the master cylinder back to the rear wheel cylinders including the lines on the front and also the rubber hoses on the front new calipers,rotors,wheel cylinders,lines and pads.

Brake line diagram


Brake Lines and Hoses
Double-walled steel line is used in the hydraulic lines between the brake master cylinder and the front tube connector, and between the brake master cylinder and the flexible brake hose at the rear wheels.
Double-flared brake lines provide good leak-proof connections.
When replacing hydraulic brake lines, hoses, or connectors, tighten all connections securely. After replacement, bleed the brake system; refer to Section 206-00 .
The wet appearance of the outer cover of the rubber brake hose is referred to as "sweating." This is a normal condition for neoprene rayon braid hose and is not a sign of leakage or cause for replacement of the hose.
