No brake fluid at right rear caliper yet plenty at left rear, minimal at fronts?

I replaced rear pads, left brake lines off and they drained out..never touched front pads or? upon reinstall, bleed master cyl both ports till no air what so ever, upon bleeding rear caliper and lines, only getting strong flow of fluid at LR and nothing at RR, and minimal pressure on both fronts, tried bleeding abs control unit, not getting flow out to some lines? tried running car up to 20 mph to see if abs would reset to home on pistons inside controller, just causes slip light on dash, shut of traction control, and no light, and no brake pressure, master cylinder has what seems to be normal pressure coming out. whats going on? Have a good amount of knowledge and experience, cant figure this one out yet?

SOURCE: 04 Focus SVT- All brakes will bleed out except the right rear..??

Have somone help you as you bleed the brakes. Have them pump the pedal 3 times and hold the pedal down with constant pressure while you crack the bleed valve open to the problem caliper. Don't let them release the pedal until you have closed the bleeder valve. Continue this process until you have fluid coming out without air. Periodacillay check the master cylinder to be sure it remains full enough so as not to allow more air in because the resivouir ran to low during the bleeding process. If when you are done and the brake light continues to be on then you will need to bleed the proportioning valve until the system balances out on line pressure.
If this works can you please give me a rating??? Thank you.

SOURCE: installed new master cly.,bench bled, bled rr,

The problem is probably that you must do the lr before moving to the front. The air in the lr will make it too spongy to bleed the front.
A wheel cylinder is only $25, so you might as well just replace it. And if you use vasoline or brake lube on the bleeder, it will not rust up on you next time.

Proportioning valves are not supposed to block a bleed. They can malfunction, but should not supposed to. And if you have the back working, that should reset the proportioning valve anyway. You can't leave the back. It must be finished.

What is next? Brake pressure is non-existent on all but front left. Pedal pressure is very hard. Replaced all calipers and master cylinder. Fluid does not exit nipple when bled on all but left front.


Its possible that your rubber lines are collapsed. I've had them keep fluid from going thru as well as not releasing pressure. See if fluid gets to caliper thru rubber. You can plug it with your finger and release pedal. If you feel vacuum and fluid flows well when you push brake, that's probably not the problem. Its somewhere to start tho.

Replaced some brake line, rear pads and one rear wheel cylinder. Now no pressure and nothing happening when trying to bleed.


Does the car have ABS ? And does it have an equalizer block for the 4 wheels ?
It sounds like the ABS has been affected, or there is an equalizer block that is stuck on the front wheels only.
Can you open the bleeder or the rear line on the master cyl and get fluid to come out by depressing the pedal ?

Replacing caliper on 2002 dodge neon


The first thing is to make sure the caliper piston is all the way in, the caliper then slides over the brake pads and bolts on, make sure you have the correct caliper on the right side, the way to know this is when caliper is on the little bleeder screw should be on the top, if it is on the bottom then wrong caliper, try the other one,

After caliper is on you will then need to bleed the brake system,
This all depends on what happened, if the brake fluid did not all leak out and caliper was just bad then before removing brake hose off old caliper pinch rubber brake line with a pair of needle nose grips or there is a line crip tool that crips hose to avoid fluid from leaking out. this makes bleeding easier , other wise you will need to make sure fluid is full and start at the right rear wheel bleeding and move to left rear then right frt and last left front, you will need to keep an eye on the level of brake fluid and add as need to keep it from going empty,
you will need some one to pump and hold brake while you bleed them, pump pedal three times and hold down while you open bleeder screw, this is to be done to every wheel about four to five time to make sure all air is out . good day. note if pedal feels low bleed again wont hurt anything just a little more fluid lost.

2005 GMC Envoy, no brake fluid is getting to the right front caliper. disconnected the brake line where the rubber line and the metal line are attached, pumped brakes and get absolutely no fluid through...


You may have a defective line on the right front brake. GM had a batch of bad lines installed on several year models. I had one collapse on mine with the caliper closed and burned my caliper, rotor and pads. Try to disconnect the metal line further back at the equalizer and see if you get fluid there. If you do replace line.

I have a 2004 Mazda MPV with some wierd brake issues. I found what appeared to be a bad caliper on front passenger side, and replaced with a new one, yet this same wheel continues to seize up. What is...


If the caliper is seizing and it is not the caliper it is the module that controls how the brake fluid is distributed. I don't have my book in front of me at the moment but when you look under teh hood on teh drivers side you will see a block that has the brake lines coming out of it. That is part of teh ABS system is one is installed and is a master brake control hub if it ABS isn't installed. being that new I would assume it was equipped with ABS. There are a couple of ways you can test if this is teh problem. If I remember correctly the MPV brakes with all 4 brakes, that means you can, as a temp test, switch the lines to see if the caliper problem changes to the different caliper. If it does then you know for a fact it is that unit and not the caliper. Also, something to consider, the caliper that is locking maybe locking because the problem is actually the caliper on the opposite side. If the caliper on the left front is stuck in the open position, on occasion that will cause too much fluid pressure to the right front giving you the impression the problem is the right side and it isn't. This is rare but certainly a possibility. As a general rule you should always replace Calipers in pairs. If you replace the right front you should replace the left front, same with the rear calipers.

My brakes will not get hard. The pedal goes to the floor. I just changed rear caliper and rotor on the drivers side.


DId you bleed the system after you changed the caliper? If the Master cylinder lost it's fluid while you were changing the caliper, then there is air in the system and you need to bleed the entire system. start with the REAR RIGHT, then the REAR LEFT and then the FRONT RIGHT and last the FRONT LEFT. make sure the master cylinder NEVER runs low on fluid and DO NOT re-use any fluid that you get out of the calipers.

Could you tell me the procedure for removeal ands reinstall new braek pads to the rear disks. thank you Dave m


Here are some procedures you can follow to replace the brake pads. 1. Clamp the rubber lines with vacuum line clamps. You can get these at your local auto parts store. 2. Loosen the bleeder screw with the proper size wrench. 3. Loosen and remove the lower caliper to bracket bolt. 4. With the proper tool, and using a pan to catch the fluid, compress the piston in. Tighten the bleeder screw. 5. Side the caliper off and remove the old brake pads. 6. Loosen and remove the caliper mounting bracket(this is the part that the brake pads slide back and forth on). 7. Remove the rotor and have it measured and resurfaced if it is thick enough. Please keep in mind that rotor thickness can have an impact on brake performance as well as a safety issue. If it is too thin, replace them. If you just slap pads on you,could possibly get a squeal or other undesirable noise from the brakes. 8. Clean and lubricate the slide pins and bracket with some caliper grease. 9. Reinstall the rotors. 10. Remount the caliper mounting bracket, and with a torque wrench, tighten the bolts to proper specs. You can get the torque specifications from the parts store as well or a shop that does brake service. 11. Reinstall new brake pads. I usually put the pad with the metal sensor on the inside and on the bottom. 12. Remount the caliper and tighten the bolts to proper specification. 13. Loosen the bleeder screw, and with the help of an assistant, bleed the air from the system, making sure the master cylinder does not go dry. You will know if there is no more air in the system if there are no air bubbles coming from the bleeder screw as well as the firmness of the brake pedal. Make sure you have plenty of brake fluid on hand. There might be a sequence in which you have to bleed the system. You can get that from the parts store or shop as well. The sequence is usually right rear, left rear, right front, left front. 14. Mount the wheels, torque them to proper specification. Also, inflate the tires to proper pressure. Low tire pressure can cause a pulling effect. There you have it and good luck.

Vibration in rear of vehicle when braks are applied


I believe that the rear discs are warped or the tires are out of round when braking. More likely, the discs. --- The following are the instructions for replacing the front and rear pads for the front/back rotors. 1999-01 Grand Cherokee Front
  1. Drain 2?3 of the brake fluid from the front reservoir. Use the bleeder screw at the front outlet port to drain the fluid. If equipped with anti-lock brakes, relieve the system pressure.
  2. Raise and safely support the vehicle.
  3. Remove the wheels.
  4. Insert a small prybar through the caliper opening and pry the caliper (using the outboard brake pad) to bottom the pistons in the caliper bore. NOTE: This will back the brake pads off of the rotor surface to facilitate the removal and installation of the caliper assembly.
  5. Pry the caliper support spring out of the caliper.
  6. Remove both caliper slide pin bushing caps and slide pins.
  7. Lift the caliper from the anchor.
  8. Using a piece of mechanics wire, support the caliper so there is not tension on the brake hose.
  9. Remove the brake pads from the caliper. Fig. 2: Installing the inward brake pad on the front caliper pistons - 1999-01 Grand Cherokee 93026g92.gif
    To install:
  10. Position the brake pads onto the caliper.
  11. Position the caliper into place on the anchor.
  12. Coat the caliper slide pins with silicone grease and torque them to 21-30 ft. lbs. (29-41 Nm). Install the slide pin bushing caps.
  13. Install the caliper support spring in the top of the caliper under the anchor; then, install the other end into the lower caliper hole. NOTE: Hold the spring in the caliper hole with your thumb while prying the spring end out and under the anchor.
  14. Fill the master cylinder with fluid and bleed the brake system.
  15. Before driving the vehicle, pump the brakes several times to seat the pads.
  16. Install the wheels.

Brake pull


After you replaced the left caliper, did it still pull right? Check your flex hoses and make sure they have plenty of fluid going through it by bleeding the line. Check both sides this way. Make sure you don't have any leaks either. Look for any kinked or leaking hard lines. While it's up in the air, check you front hub assys. for movement. Check suspension and steering components as well.
