Bleeding the brakes 91 Chevy s10

I found a small rubber cover on an opening right above where the brake hose runs into the wheel. Is this what I am looking for. I dont see any screws to loosen. Maybe I'm in the wrong spot. I'm looking at the rear wheels

Replace right front brake line

Depends if you are talking only the flex hose near the caliper (very easy), or the hard line (fairly difficult). The flex line just requires buying a new hose & bracket clips and bolting them on. I'm guessing the steel brake line corroded somewhere near the bottom of the firewall where mine did. I found it easier to just reroute the new line across the top of the firewall just under the hood gasket. It is very difficult, if not impossible to remove the line and replace it to the factory location without disturbing the other 3 brake lines.

My suggestion is to use a bolt culler and cut the line as far down the firewall as you can from above and then as far up the driver side firewall from underneath. Run the new line from the ABS module, across the top back of the engine compartment and then down the passenger front wheel well, and wrap it around the bottom of the wheel well to the factor bracket that holds the flex line. Use metal clips with the rubber lining to screw the brake line to the firewall and make sure it can't vibrate against anything. Use rubber hose around the brake line at any location that you can't avoid contact through vibration.

There's obviously a lot more to be said about how to bend brake line, make fittings, and bleeding brakes that I won't get into here because it sounds like the main question was how to tackle this tough fix. I would seriously consider thoroughly inspecting the other brake lines and the fuel line where they come up the firewall from under the car. I found several more locations just waiting to blow like my front right line did and decided to replace all the brake lines.

I dont know how too bleed my brakes on my 89 omni any tips

You'll need a helper to help push the brake pedal. Start at the right rear, open the bleeder, have your helper push slowly and steadily down on the brake pedal. Close the bleeder. Have your helper take foot off the brake pedal. Repeat this process until either the fluid is clean/clear or there is no more air coming out of the lines. Continue this process at the left rear, then the right front, and finish at the left front. Let me know if you have any questions and I'll do my best to answer them. Thank you for using!

How do you bleed the brake system on 2003 suzki grand yitara 4x4 with abs brakes

The hydraulic brake system must be bled any time one of the brake lines is disconnected or air enters the system. There are two ways to bleed the system; pressure bleeding or manual bleeding. Both procedures will be given here, although pressure bleeding requires the use of some fairly expensive equipment (a pressure tank) and is seldom used. Both methods are equally effective.The correct bleeding sequence is: left front, right front, left rear, and right rear. On master cylinders equipped with a bleeder valve, bleed the master cylinder last.
  1. Clean the top of the master cylinder, remove the cover, and attach the pressure bleeding adapter.
  2. The spring-loaded plunger on the front of the proportioning valve must be depressed while bleeding. Wire or tape can be wrapped around the valve to hold the plunger in.
  3. Check the pressure bleeder reservoir for correct pressure 20-29 psi (137-206 kPa) and fluid level, then open the release valve.
  4. Fasten a bleeder hose to the wheel cylinder or caliper bleeder nipple and submerge the free end of the hose in a transparent receptacle. The receptacle should contain enough brake fluid to cover the open end of the hose.
  5. Open the wheel cylinder or caliper bleeder nipple and allow the fluid to flow until all bubbles disappear and an uncontaminated flow exists.
  6. Close the nipple, remove the bleeder hose and repeat the procedure on the other wheel cylinders according to the sequence.

MANUAL BLEEDING(see Figures 1, 2 and 3)An alternative to the pressure method of bleeding requires two people to perform; one to depress the brake pedal and the other to open the bleeder nipples.
  1. Clean the top of the master cylinder, and then remove the cover and fill the reservoir with clean brake fluid.
  2. To prevent squirting fluid replace the cover.
  3. The spring-loaded plunger on the front of the proportioning valve must be depressed while bleeding. Wire or tape can be wrapped around the valve to hold the plunger in.
  4. Install a box end wrench on the left front bleeder screw.
  5. Attach a length of small diameter, clear vinyl tubing to the bleeder screw. Submerge the other end of the rubber tubing in a glass jar partially filled with clean brake fluid. Make sure the rubber tube fits on the bleeder screw snugly or you may be squirted with brake fluid when the bleeder screw is opened.
  6. Have your friend slowly depress the brake pedal. As this is done, open the bleeder screw half a turn and allow the fluid to run through the tube. Close the bleeder screw, then return the brake pedal to its fully released position.
  7. Repeat this procedure until no bubbles appear in the jar. Refill the master cylinder.
  8. Frequently check the master cylinder level during this procedure. If the reservoir runs dry, air will enter the system and the bleeding will have to be repeated.

Hope helps.

Is the master cylinder good? a bad master can cause this also did you bleed the master first before bleeding at the wheel and also make sure the bleeder screw is clean, if the hose is good then theres only a few things, a bad master or a master that wasnt bleed, try bleeding the master first then try rebleeding the brakes.

the master cyclinder is divided into diagonal wheels. meaning that each line from the master cyclinder provides fluid to a front wheel and rear wheel. on the front resevoir of the master cyclinder it would be perhaps the left front and right rear brake for example. you need to block the lines going to the rear wheels independently and then bleed the brakes again starting with the wheel furthest from the master cyclinder.

Bleeding the brakes after new pads are installed...

If you have help, you can simply place a clear tube over the nipple on each wheel and while your assistant pumps the brakes, allow the old fluid to be pushed out by the new. Start with the rear passenger, then rear driver side then the front. If you do not have help, kits can be purchased that allow you to do this as a one man job.

was the line going to the rear? if so on the front of thepropotional valve is a pin onder the rubber cover it should be in, if not you will have to remove the, one wire, sensor and look inside. there should be a little knoch in the center if not it will be to the front, use a small pick to slide it to the center replace the sensor and try to re-bleed.

Brake pedal goes to the floor

Hi, Depending on where the leak was it probably allowed air into the brake lines, so you need to bleed the brakes at each wheel. Do it one at a time, and you may have to pump the brakes several times if your leak was at the front to get the air out all the way to the back. Best of luck to you!

Bleeding the brakes on a 91 Chevy S10 2wd

if you look on the inside of the wheel you will see what looks like greese fittings you need to have somebody pump and hold the brakies and then you need to slowly crack it open by unscrewing it untill you get air then wait till it stops t5hen tighten it and pump the brakes again and do this again dont let the brake fluid run out of the resivore ok pretty soon you will feel the brake pedle start to get hard then do this a couple of more times and then you will be done ok best regardss mike
