Question about 2004 Honda CRF 250 R

1 Answer

I cannot bleed the front brakes on a 1989 Honda 350 atv. I have filled the reservoir and get fluid down to the bleeder valves but I get no pressure from the lever. The wheels were froze from the brakes being stuck? I was able to free the drums by hammering on them and blowing out debris. They spin freely now but there is no brakes.

I have an 01 GMC Jimmy 4.3L 4WD & we are trying to bleed the brakes but the scanner says my vehicle is going 3MPH so we manually bleed the brakes but the pedals still easily is pushed to the floor.


Bad master cylinder . What are you using a scan tool for ? No need Unless your Installing a new Electro-Hydraulic Control Unit (EHCU) or new Brake Pressure Modulator Valve (BPMV).
Hydraulic Brake System Bleeding (Manual)
Caution: Refer to Brake Fluid Irritant Caution in the Preface section.
Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in the Preface section.
Place a clean shop cloth beneath the brake master cylinder to prevent brake fluid spills.
With the ignition OFF and the brakes cool, apply the brakes 3-5 times, or until the brake pedal effort increases significantly, in order to deplete the brake booster power reserve.
If you have performed a brake master cylinder bench bleeding on this vehicle, or if you disconnected the brake pipes from the master cylinder, you must perform the following steps:
3.1. Ensure that the brake master cylinder reservoir is full to the maximum-fill level. If necessary add GM approved brake fluid from a clean, sealed brake fluid container. Refer to Fluid and Lubricant Recommendations.
If removal of the reservoir cap and diaphragm is necessary, clean the outside of the reservoir on and around the cap prior to removal.
3.2. With the rear brake pipe installed securely to the master cylinder, loosen and separate the front brake pipe from the front port of the brake master cylinder.
3.3. Allow a small amount of brake fluid to gravity bleed from the open port of the master cylinder.
3.4. Reconnect the brake pipe to the master cylinder port and tighten securely.
3.5. Have an assistant slowly depress the brake pedal fully and maintain steady pressure on the pedal.
3.6. Loosen the same brake pipe to purge air from the open port of the master cylinder.
3.7. Tighten the brake pipe, then have the assistant slowly release the brake pedal.
3.8. Wait 15 seconds, then repeat steps 3.3-3.7 until all air is purged from the same port of the master cylinder.
3.9. With the front brake pipe installed securely to the master cylinder, after all air has been purged from the front port of the master cylinder, loosen and separate the rear brake pipe from the master cylinder, then repeat steps 3.3-3.8.
3.10. After completing the final master cylinder port bleeding procedure, ensure that both of the brake pipe-to-master cylinder fittings are properly tightened.
Fill the brake master cylinder reservoir with GM approved brake fluid from a clean, sealed brake fluid container. Ensure that the brake master cylinder reservoir remains at least half-full during this bleeding procedure. Add fluid as needed to maintain the proper level.
Clean the outside of the reservoir on and around the reservoir cap prior to removing the cap and diaphragm.
Install a proper box-end wrench onto the RIGHT REAR wheel hydraulic circuit bleeder valve.
Install a transparent hose over the end of the bleeder valve.
Submerge the open end of the transparent hose into a transparent container partially filled with GM approved brake fluid from a clean, sealed brake fluid container.
Have an assistant slowly depress the brake pedal fully and maintain steady pressure on the pedal.
Loosen the bleeder valve to purge air from the wheel hydraulic circuit.
Tighten the bleeder valve, then have the assistant slowly release the brake pedal.
Wait 15 seconds, then repeat steps 8-10 until all air is purged from the same wheel hydraulic circuit.
With the right rear wheel hydraulic circuit bleeder valve tightened securely, after all air has been purged from the right rear hydraulic circuit install a proper box-end wrench onto the LEFT REAR wheel hydraulic circuit bleeder valve.
Install a transparent hose over the end of the bleeder valve, then repeat steps 7-11.
With the left rear wheel hydraulic circuit bleeder valve tightened securely, after all air purged from the left rear hydraulic circuit, install a proper box-end wrench onto the RIGHT FRONT wheel hydraulic circuit bleeder valve.
Install a transparent hose over the end of the bleeder valve, then repeat steps 7-11.
With the right front wheel hydraulic circuit bleeder valve tightened securely, after all air has been purged from the right front hydraulic circuit, install a proper box-end wrench onto the LEFT FRONT wheel hydraulic circuit bleeder valve.
Install a transparent hose over the end of the bleeder valve, then repeat steps 7-11.
After completing the final wheel hydraulic circuit bleeding procedure, ensure that each of the 4 wheel hydraulic circuit bleeder valves are properly tightened.
Fill the brake master cylinder reservoir to the maximum-fill level with GM approved brake fluid from a clean, sealed brake fluid container.
Slowly depress and release the brake pedal. Observe the feel of the brake pedal.
If the brake pedal feels spongy, repeat the bleeding procedure again. If the brake pedal still feels spongy after repeating the bleeding procedure, perform the following steps:
21.1. Inspect the brake system for external leaks. Refer to Brake System External Leak Inspection.
21.2. Pressure bleed the hydraulic brake system in order to purge any air that may still be trapped in the system.
Turn the ignition key ON, with the engine OFF. Check to see if the brake system warning lamp remains illuminated.
Important: If the brake system warning lamp remains illuminated, DO NOT allow the vehicle to be driven until it is diagnosed and repaired.
If the brake system warning lamp remains illuminated, refer to Symptoms - Hydraulic Brakes

How to bleed clutch 2007 compass


GRAVITY BLEEDING CLUTCH HYDRAULIC CIRCUIT

1. Verify fluid level in brake master cylinder. Top off with DOT 3 brake fluid as necessary. Leave cap off.

2. Raise vehicle on hoist.

3. Remove bleed port protective cap and install suitable size and length of clear hose (4) to monitor and divert fluid into suitable container.

4. Open up the bleed circuit by turning the thumb screw (3) counter clockwise this will start the air purge and fluid fill process.

5. Lower vehicle, but only enough to gain access to and fill the brake master cylinder. NOTE: Do not allow clutch master cylinder to run dry while fluid exits bleed port.

6. Top off brake master cylinder fluid level while air is purged and fluid drains from bleed port. Continue this until no air bubbles are seen and a solid column of fluid exists.

7. Close hydraulic bleed circuit, remove drain hose and replace dust cap on bleed port.

8. From driver's seat, actuate clutch pedal 60-100 times.

9. Apply parking brake. Start engine and verify clutch operation and pedal feel. If pedal feels fine and clutch operates as designed, stop here. If pedal still feels spongy or clutch does not fully disengage, excessive air is still trapped within the system, most likely at the master cylinder.

10. Top off brake master cylinder fluid level with DOT 3 brake fluid as necessary.

POWER BLEEDING CLUTCH HYDRAULIC CIRCUIT

1. Remove reservoir cap and connect bleeder cap to reservoir. NOTE: Use Bleeder Cap/Modified reservoir cap adapter Snap-on #901-059 or equivalent.

2. Connect service filling machine to bleeder cap. NOTE: Use Service Filling Machine/Brake power bleeder Brake power bleeder or equivalent.

3. Service filling machine should be pressurized to at least 2.5 bar (36 PSI).

4. Remove dust cap from bleeder valve and connect the transparent bleeder hose to bleeder valve.

5. Place the other end of hose in the bleeder container to capture the used fluid. The end of the hose MUST be submerged in the DOT 3 brake fluid.

NOTE: Use Bleeder Container To capture hydraulic fluid and Transparent Bleeder Hose To route fluid to container.

6. Turn on the service filling machine.

7. Crack open the bleeder valve (3).

8. Allow fluid to flow out of bleed port until no more air bubbles can be seen in the transparent bleeder hose.

9. Once fluid is free of air bubbles; make 15 quick actuations between clutch pedal stop positions.

10. Close the bleeder valve and disconnect the service filling machine.

11. To remove remaining air, actuate pedal 10 times slowly between pedal stop positions.

12. Check clutch pedal to see if vehicle is properly bled.

13. If vehicle is not properly bled, repeat procedure.

14. Remove bleeder cap from reservoir and replace reservoir cap.

15. Disconnect transparent bleeder hose from bleeder valve and replace dust cap.

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.
PRESSURE BLEEDING
  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.

How do i bleed the brakes on a 99 ford expedition?


on the brake calipers ther is a bleeder screw. It looks like a grease fitting.1) fill brake fluid 2) have a helper pump the brake pedal ( vehicle not running ) 6 - 8 times to the floor and release then press pedal to the floor and hold with foot pressure pressing down. 3) at this time loosen the bleeder valve and the pressure and air will release,( do not allow brake pedal to release or come up, continue to hold to the floor ! ) after pressure and any noticeable air bubbles and no more fluid comes out then this is the time to tighten or (close ) the bleeder screw. 4) continue this process untill no visable air bubbles are present, IT IS VERY IMPORTANT THAT YOU CHECK THE BRAKE FLUID RESERVOIR AFTER TWO BLEEDINGS AND FILL AS NECESSARY ! 5) Continue the procedure on the opposite side. Do the two front wheels and the rear wheels as a pair as the brake system is a two part system, FRONT & REAR

What do you mean by gravity bleeding the brakes/


For gravity bleeding the master cylinder must be higher then the calipers or wheel cylinders. Gravity bleeding is as simple as filling the reservoir (leave the lid off) and opening the brake bleeders. Do not let the reservoir go empty check it periodically or you will have air in the system again. You may want to put the wheel cylinders or calipers in a pan and make sure the bleeders are pointing up.
