Brake ware wheel cylinder need the size of the bleeder screw, also thread size. please help cant seem to find it anywhere. I want use a speed bleeder instead of the one that comes with it
SOURCE: Bleeding brakes
No need to run the engine. Start the bleed procedure from the caliper farthest from the master cylinder, and work toward it. This means bleed the passenger rear first, then the driver rear, then passenger front, then driver front. Don't stop bleeding any caliper until you get three or so consecutive streams of air-free fluid through the bleeder. Monitor the level of fluid in the cylinder, and be sure the cap is on while bleeding - only open it to add additional fluid as needed.

5 Inspect Brake Fluid Type Brake fluid loss or contamination 10 Inspect Master Cylinder (Brake System) Worn or leaking brake master cylinder. 11 Inspect Brake Power Booster Damaged booster vacuum line/check valve, or diaphram
SOURCE: I can't bleed the rear brakes on 91 Explorer
Brakes is brakes, my friend. If you know how to bleed brakes, there is nothing special about it that should not be pointed out in the Hanes book.
Could be the bleeder is partially plugged with muck, either from the outside, or the inside. Unscrew it and make sure it blows clear. If it doesnt, then the wheel cylinder may be full of muck. Same thing probably would happen to calipers, but I've never torn into a caliper before. Probably better to replace than attempt repair.
SOURCE: spongy brakes
Does sound like you need a new master cylinder. On a 2000 you wont need to back bleed. You will just need to follow the instruction and bleed the master and all four points. you will probably need to bleed the ABS block and proportioning valve but only if they have bleeders on them.
SOURCE: tried to bleed brakes by loosening the brake lines
You need to have the broken Bleeder screws replaced or the wheel cylinders replaced. You can't bleed the brakes by loosening the brake lines all it will do is bleed the brake lines.The bleeder screws allow the fluid to flow through the wheel cylinders or calipers flushing the air out.
Print
For vehicles equipped with an Anti-lock Brake System (ABS), please refer to the ABS bleeding procedure at the end of this section.
The purpose of bleeding the brakes is to expel air trapped in the hydraulic system. The system must be bled whenever the pedal feels spongy, indicating that compressible air has entered the system. It must also be bled whenever the system has been opened or repaired. If you are not using a pressure bleeder, you will need a helper for this job.
WARNING
Never reuse brake fluid which has been bled from the brake system.
MASTER CYLINDER
See Figure 1
If the master cylinder is off the vehicle, it can be bench bled.
Fig. Fig. 1: Attach bleeding tubes to the master cylinder and position them as shown
PRESSURE BLEEDING
When bleeding the brakes, air may be trapped in the brake lines or valves far upstream, as much as 10 feet from the bleeder screw. Therefore, it is very important to have a fast flow of a large volume of brake fluid when bleeding the brakes, to make sure all of the air is expelled from the system.
On Cirrus, Stratus, Sebring convertible and Breeze models, the following wheel sequence should be used to ensure that all the air is removed from the system:
Left rear wheel
Right front wheel
Right rear wheel
Left front wheel
On Sebring coupe and Avenger models, the following wheel sequence should be used to ensure that all the air is removed from the system:
Right rear wheel
Left front wheel
Left rear wheel
Right front wheel
MANUAL BLEEDING
See Figure 2
Proper manual bleeding of the hydraulic brake system will require the use of an assistant.
On Cirrus, Stratus, Sebring convertible and Breeze models, the following wheel sequence should be used to ensure that all the air is removed from the system:
Left rear wheel
Right front wheel
Right rear wheel
Left front wheel
On Sebring coupe and Avenger models, the following wheel sequence should be used to ensure that all the air is removed from the system:
Right rear wheel
Left front wheel
Left rear wheel
Right front wheel
