Question about 2003 Chevrolet Malibu

2 Answers

2003 chevy malibu. brakes go to the floor.

So i checked my g/f's car. brake fluid looked empty. filled the resivior, didnt help. bleed out all 4 brakes, no change. the brakes will go to the floor, but pumping them quickly will stiffen them up, however that lasts for about 4 seconds after the stop, then they go right to the floor again. seems like they get pressure, they just dont retain it. should i go ahead and replace the master cylinder? or should i take off the drums and replace the wheel cylinders?

Take off the drums and look for leakage in the cylinders,you have a leak somewhere if the fluid was low. It could be the master cylinder too, the one on my s-10 started leaking slowly. You also may still have some air in the lines, but you do have a leak. look for wet areas around the floor/ body/ under the car.

Master cyl. is "bypassing" replace it, but make sure you "bench bleed " it first !
After that then have someone get in car and pump up brakes, you then bleed them one at a time.
MAKE sure not to let the master cyl. res. go dry or you will be there ALL DAY bleeding !

My brake pedal goes all the way to the floor there is no any brake oil leak i replace the brake master cylinder i bleed the system but still the same what is the correct procedure to bleed brake system...


fill master cylinder, start at right rear. the way I do it is make sure cap is back on master cylinder. pump the brakes a few times then hold them. have another person open the bleeder valve at the tires until brakes go to floor. hold them down until bleeder is retightened but be sure master cylinder is not out of fluid. then go to left rear and do the same procedure, then right front, then left front. check fluid and if air is all out there should be brakes. good-day ! THIS IS HOW I HAVE ALWAYS DONE IT ! heres a little trick of sorts. you can change a master cylinder, and if you bench bleed it first. and no fluid is lost from the master cylinder lines you do not need to bleed the whole system. but make sure cylinder is full of fluid before putting on vehicle and all air is out of master cylinder.

I have a 2004 Land cruiser and changed the right rear brake cyl and brake shoes . What is the proper procedure to bleed the rear brake system. Thank you for your help.


  1. Check the fluid level in the reservoir after bleeding each wheel. Add DOT3 fluid, if necessary.
  2. If the master cylinder was disassembled or if the reservoir becomes empty, bleed the air from the master cylinder as follows:
    1. Disconnect the brake lines from the master cylinder.
    2. Slowly depress the brake pedal and hold it.
    3. Block off the outlet plug with your finger, and release the brake pedal.
    4. Repeat 3 or 4 times.

  3. Bleed the brake starting with the one furthest from the reservoir and then the next furthest, etc.
  4. Depress the brake pedal several times, then loosen the bleeder plug with the pedal held down.
  5. At the point when fluid stops coming out, tighten the bleeder plug to 11 Nm (8 ft. lbs.), then release the brake pedal.
  6. Repeat until all the air in the fluid has been bled out.
  7. Repeat the procedure to bleed the air out of brake line for each wheel.
  8. Check the fluid level and add DOT3 fluid if necessary.

What are the proper steps to bleeding your brakes on a 1990 vw golf deisel


For left hand drive vehicles: (If the car does not have ABS system you do not need any diagnostic equipment!)

IMPORTANT NOTE: You need using diagnostic equipment connected to the data link connector of the car in order to bleed the ABS block. Follow instructions by scantool equipment for bleeding the ABS block.


1. This bleeding procedure requires two people. Remove the brake system reservoir cap, and fill up with new brake fluid until "MAX" level is reached.
2. Lift the car, or use a channel for access under vehicle.
3. Put the gearbox in "N" - Neutral position, or in "P" - Parking position for automatic transmission.
4. Start the engine and push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor.
5. Begin with the rear right wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
6. Repeat steps no.#4 and no.#5 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.

IMPORTANT NOTE: All the time check the brake fluid level in the brake system reservoir, and fill up if necessary!

7. Push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor, engine idling.
8. Continue with the rear left wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
9. Repeat steps no.#7 and no.#8 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.

IMPORTANT NOTE: All the time check the brake fluid level in the brake system reservoir, and fill up if necessary!

10. Push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor, engine idling.
11. Continue with the front right wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
12. Repeat steps no.#10 and no.#11 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.

IMPORTANT NOTE: All the time check the brake fluid level in the brake system reservoir, and fill up if necessary!

13. Push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor, engine idling.
14. Continue with the front left wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
15. Repeat steps no.#13 and no.#14 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.
16. Now the brakes are bleeded. Check the brake fluid level in the reservoir. Fill up with new brake fluid until "MAX" level is reached. Put back the brake reservoir cap.
17. Test the car brake system. The brake pedal movement no more than 1/3 of total stroke until the floor, when brake pedal is applied. Maximum admissible is 1/2 of total stroke.

1994 corolla...brake pedal goes to the floor after changing lines,brake booster and the master...is there bleeder valves im missing?


Assumeing you have no big leaks in the new brake lines witch you would see because there would brake fluid all over the ground I would say you didn;t bench bleed the new master cylinder There is air in this part when you buy it and you need to get it out before it will work Heres how you do it first you need a kit it consests of plugs that you screw into the holes that the brake lines go into but they have fittings for hoses to plug on to them you put the master cylinder into a vice screw the plugs into the holes put the hoses on the fittings and put the other end of the little hoses into the cylinder resivior fill the resiviors with brake fluid then take some kind of a tool i like to use a 6 inch 3/8 ths socket extentoin because not sharp but you could use a screw driver And push the piotion in from the back of the unit repeataly until you see now more air bubbles coming out of the two little hoses that are in the resiviors like ten or so pushes Then reinstall hook up the lines and bleed at wheel cylinders with wheel cylinder bleeding always start at the fertist wheel and work your way back to the closetes wheel Its not as hard as it may sound good luck

Unable to bleed the brakes how do you bleed the reakes out


First fill the brake resivior then have someone pump pedal three times and hold pedal down, while you start at the right rear wheel open the bleeder screw and let fluid out and then close make sure who ever pumps pedal keeps preasure on it as you open bleeder because pedal will drop they must push and follow pedal, after you clsoe bleeder you then have them pump pedal again three times you will do this four to five times on each wheel make sure to check fluid level after each wheel is bleed, after the left rear you move to left rear then right front then last is left front, hope this helps.

My brake fluid was empty and brake pedal goes to floor.I filled it but still seems the same


Hello, my name is Ben. If the fluid reservoir was empty there is most likely air in the system now. At a minimum you will need to bleed the brakes. Also, you need to look carefully behind each wheel and check for leaks.

Air in braking system?


Then master cylinder maybe damaged from the contamination,you may need to replace the master,try bleeding the master cylinder at the brake lines to clean it out,then start at the right rear wheel,then the left rear wheel,then the right front wheel,and then the left front wheel,do this in order.

No pressure when I brake.


I would suspect there is either a crack in your brake line. the fluid has to go somewhere if youre having to refill the reservior. Maybe they didnt bleed them after the work was done, and had an air bubble and when you applied pressure is blew out a fitting. needs to be checked out though for sure!

How do i bleed the brake system


First, before you do the bleeding, did you "open" any of the lines? Was there a caliper replaced?

If no line was opened, you do not need to bleed the brakes.

If so, please let me know and I will post the bleed procedures for you.

Why are you thinking about bleeding the brakes? Spongy brake pedal?
