Question about 1985 Volkswagen Cabriolet

1 Answer

While bleeding the brakes on my 1985 vw cabriolet, I noticed that the left rear wheel cylinder and right front caliper had very little fluid comming out of them and the other two were bleeding great. What would cause this to happen? I would think the master cylinder or could it be something else?

You have whats called a triangulated brake system (2xfront/1x rear)with a brake compensating valve( just in front of the rear axle)which helps to stop the rear wheels from locking,because of the different pipe lengths it is normal for this to happen.but for the life of me i cannot remember which wheel you srtart to bleed,and in what order....... (stopped working for vw 10 years ago)

I have replaced 3 disc brake calipers on my 2001 pt cruiser. after bleeding all 4 brakes 3 times, I started the car and brake pedal goes to floor. is my brake booster shot?


Michael:

You must start bleeding the brakes at the wheel farthest from the master cylinder (usually the right rear), then the next farthest from the master cylinder, then the next, then the closest. If your master cylinder is at the left front of the car, start with the right rear, then the left rear, then the right front, then the left front. If you don't bleed the brakes in the correct order, you are just shifting the air in the lines from one line to another. Make sure that you close the bleeder before letting the brake pedal up, and the engine should not be running when you bleed the brakes... Make sure that the emergency brake is off. Make sure that the master cylinder does not run out of brake fluid at any time that you are bleeding the brakes.

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.

After changing front caliper on car how the right way to bleed system


Proper way is to bleed the entire system. IF your master cylinder DID NOT run lut of fluid then you can get by with just bleedign the one caliper you replaced. Otherwise you need to make sure the master cylinder stays full and start at the furthest away wheel, generally the rear right. then do the rear left. then if you have ABS, the abs module. then the front right and finally the front left. DO NOT re-use any brake fluid.

Bleeding procedure: use enough tubing to route the fluid into a suitable container. OPEN the bleed valve and have someone press the brake pedal. While they hold the pedal down, close the valve. Let off the brake pedal and do it as many times as needed to remove all the air. Check the master cylinder often to make sure it has fluid.

How to bleed brakes on 1997 Saturn


The brake system bleeding procedure differs for ABS and non-ABS vehicles. The following procedure pertains only to non-ABS vehicles. For details on bleeding ABS equipped vehicles, refer to the ABS procedures later in this section.

WARNING Make sure the master cylinder contains clean DOT 3 brake fluid at all times during the procedure.
  1. The master cylinder must be bled first if it is suspected of containing air. Bleed the master cylinder as follows:
    1. Position a container under the master cylinder to catch the brake fluid.
    2. Loosen the left front brake line (front upper port) at the master cylinder and allow the fluid to flow from the front port.
    3. Connect the line and tighten to 24 ft. lbs. (32 Nm).
    4. Have an assistant depress the brake pedal slowly one time and hold it down, while you loosen the front line to expel air from the master cylinder. Tighten the line, then release the brake pedal. Repeat until all air is removed from the master cylinder.
    5. Tighten the brake line to 24 ft. lbs. (32 Nm) when finished.
    6. Repeat these steps for the right front brake line (rear upper port) at the master cylinder.
WARNING Do not allow brake fluid to spill on or come in contact with the vehicle' finish, as it will remove the paint. In case of a spill, immediately flush the area with water.
  1. If a single line or fitting was the only hydraulic line disconnected, then only the caliper(s) or wheel cylinder(s) affected by that line must be bled. If the master cylinder required bleeding, then all calipers and wheel cylinders must be bled in the proper sequence:
    1. Right rear
    2. Left front
    3. Left rear
    4. Right front
  2. Bleed the individual calipers or wheel cylinders as follows:
    1. Place a suitable wrench over the bleeder screw and attach a clear plastic hose over the screw end.
    2. Submerge the other end in a transparent container of brake fluid.
    3. Loosen the bleed screw, then have an assistant apply the brake pedal slowly and hold it down. Close the bleed screw, then release the brake pedal. Repeat the sequence until all air is expelled from the caliper or cylinder.
    4. When finished, tighten the bleed screw to 97 inch lbs. (11 Nm) for the front, or 66 inch lbs. (7.5 Nm) for the rear.
  3. Check the pedal for a hard feeling with the engine not running. If the pedal is soft, repeat the bleeding procedure until a firm pedal is obtained.

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.

How to bleed brakes on 2002 toyota sienna


Here is the procedure from the service manual. I would add just one thing. Do each wheel in this order

  1. right rear wheel
  2. left rear wheel
  3. right front wheel
  4. left front wheel
BLEEDING

HINT: If any work is done on the brake system or if air in the brake lines is suspected, bleed the air from the system.

NOTICE: Do not let brake fluid remain on a painted surface. Wash it off immediately.


a)FILL BRAKE RESERVOIR WITH BRAKE FLUID Fluid:SAE J1703 or FMVSS No. 116 DOT3

b)BLEED MASTER CYLINDER HINT: If the master cylinder has been disassembled or if the reservoir becomes empty, bleed the air from the master cylinder.

c)Disconnect the brake lines from the master cylinder. SST 09023-00100 Slowly depress the brake pedal and hold it.

Block off the outlet plug with your finger and release the brake pedal.
Repeat (b) and (c) 3 or 4 times.


BLEED BRAKE LINE

1. Connect the vinyl tube to the caliper or wheel cylinder bleeder plug.
2. Depress the brake pedal several times, then loosen the bleeder plug with the pedal held down.
3. At the point when fluid stops coming out, tighten the bleeder plug, then release the brake pedal. Torque: (Bleeder plug) Front brake caliper
: 8.3 Nm (85 kgf-cm, 74 inch lbs.) Rear wheel cylinder: 8.5 Nm (87 kgf-cm, 75 inch lbs.)
4. Repeat (b) and (c) until all the air in the fluid has been bled out.
5. Repeat the above procedure to bleed the air out of the brake line for each wheel.

CHECK FLUID LEVEL IN RESERVOIR Check the fluid level and add fluid if necessary. Fluid: SAE J1703 or FMVSS No. 116 DOT3

Bleeding brake system how?


BLEED BRAKE SYSTEM

Make sure one end of the Jeep is raised (starting with the rear end) and secure on jack stands and the wheels on each side have been removed. If you have been working on the brakes, this should already be done.

Connect a clear rubber tube to the bleeder valve on the right rear brake caliper. Start with this end and side because it is farthest from the master cylinder.Place the tube's other end into a container partially filled with brake fluid.

Open the bleeder valve on the caliper and have an assistant press on the brake pedal inside the Jeep. Look for a mixture of air and fluid to come out of the valve. Once all the air is purged and the fluid runs cleanly from the valve, close the screw and remove the tube.

Repeat the process for all four brakes. Move to the left rear next, followed by the right front and the left front. If you need to, reconnect the Jeep's rear wheels and lower the rear end before raising the front end and removing those wheels.

Check the level of fluid in the master cylinder periodically as you bleed the brakes. If the level drops below the needed fill line, add more fluid. Use fresh fluid, not any that you have bled from the brakes.

Start the Jeep's engine after bleeding all the brakes and press on the brake pedal. You might need to do this repeatedly to seat new brake pads you just installed. Turn off the engine and hold down on the pedal. Bleed the brakes again if the pedal sink within 15 to 20 seconds.

Start from right rear, then, left rear, right front, left front. Fill master cylinder. Have helper sit in car, have helper hold brake pedal down. open bleed screw. fluid and air comes out. close screw. release brake pedal. Continue until no air comes out. Move to next wheel. Keep an eye on master cylinder fluid level after each wheel.

Brake pad replacement


You will need to bleed all four corners, starting at the right rear, then left rear, then right front, then left front. Your bleed procedure always goes from the wheel farthest from the master cylinder, to the closest. By bleeding only the rear brakes, you've gotten air out back there, but not necessarily any air that might have moved farther forward. Bleed your rears again, and then move forward to bleed the fronts, and see if that helps.
