BRAKE SYSTEM BLEEDING Diagonal Split System MASTER CYLINDER

  1. Refill the master cylinder reservoir.
  2. Push the plunger several times to force fluid into the piston.
  3. Continue pumping the plunger until the fluid is free of the air bubbles.
  4. Plug the outlet ports and install the master cylinder.
COMPLETE SYSTEM
  1. Fill the master cylinder with fresh brake fluid. Check the level often during the procedure.
  2. Starting with the right rear wheel, remove the protective cap from the bleeder, if equipped, and place where it will not be lost. Clean the bleed screw. When bleeding the brakes, keep face away from the brake area. Spewing fluid may cause facial and/or visual damage. Do not allow brake fluid to spill on the vehicle's finish; it will remove the paint.
  3. If the system is empty, the most efficient way to get fluid down to the wheel is to loosen the bleeder about 1?2 - 3?4 turn, place a finger firmly over the bleeder and have a helper pump the brakes slowly until fluid comes out the bleeder. Once fluid is at the bleeder, close it before the pedal is released inside the vehicle. NOTE: If the pedal is pumped rapidly, the fluid will churn and create small air bubbles, which are difficult to remove from the system. These air bubbles will eventually congregate resulting in a spongy pedal.
  4. Once fluid has been pumped to the caliper or wheel cylinder, open the bleed screw again, have the helper press the brake pedal to the floor, lock the bleeder and have the helper slowly release the pedal. Wait 15 seconds and repeat the procedure (including the 15 second wait) until no more air comes out of the bleeder upon application of the brake pedal. Remember to close the bleeder before the pedal is released inside the vehicle each time the bleeder is opened. If not, air will be induced into the system.
  5. If a helper is not available, connect a small hose to the bleeder, place the end in a container of brake fluid and proceed to pump the pedal from inside the vehicle until no more air comes out the bleeder. The hose will prevent air from entering the system.
  6. Repeat the procedure on remaining wheel cylinders in order:
    1. Step 1: Left front
    2. Step 2: Left rear
    3. Step 3: Right front
  7. Hydraulic brake systems must be totally flushed if the fluid becomes contaminated with water, dirt or other corrosive chemicals. To flush, bleed the entire system until all fluid has been replaced with the correct type of new fluid.
  8. Install the bleeder cap(s) on the bleeder to keep dirt out. Always road test the vehicle after brake work of any kind is done.
Teves® Anti-lock Brake System FRONT BRAKES
  1. Turn the ignition switch OFF throughout this procedure.
  2. Using at least 50 lbs. pressure on the brake pedal, depress the pedal at least 25 times; a noticeable change in pedal pressure will be noticed when the accumulator is discharged.
  3. Remove the reservoir cap. Check and/or refill the master cylinder reservoir.
  4. Using the bleeder adapter tool, install it onto the fluid reservoir.
  5. Attach a diaphragm type pressure bleeder to the adapter and charge the bleeder to 20 psi.
  6. Using a transparent vinyl tube, connect it to either front wheel caliper and insert the other end in a beaker 1?2 full of clean brake fluid.
  7. Open the bleeder valve 1?2 - 3?4 turn and purge the caliper until bubble free fluid flows from the hose.
  8. Tighten the bleeder screw and remove the bleeder equipment.
  9. Turn the ignition switch ON and allow the pump to charge the accumulator.
  10. After bleeding, inspect the pedal for sponginess and the brake warning light for unbalanced pressure; if either of the conditions exist, repeat the bleeding procedure.
REAR BRAKES
  1. Turn the ignition switch OFF.
  2. Using at least 50 lbs. pressure on the brake pedal, depress the pedal at least 25 times; a noticeable change in pedal pressure will be noticed when the accumulator is discharged.
  3. Check and/or refill the master cylinder reservoir.
  4. Turn the ignition switch ON and allow the system to charge. NOTE: The pump will turn OFF when the system is charged.
  5. Using a transparent vinyl tube, connect it to a rear wheel bleeder valve and insert the other end in a beaker 1?2 full of clean brake fluid.
  6. Open the bleeder valve 1?2 - 3?4 turn and slightly depress the brake pedal for at least 10 seconds or until air is removed from the brake system. Close the bleeder valve. NOTE: It is a good idea to check the fluid level several times during the bleeding operation. Remember, depressurize the system before checking the reservoir fluid.
  7. Repeat the bleeding procedure for the other rear wheel.
  8. After bleeding, inspect the pedal for sponginess and the brake warning light for unbalanced pressure; if either of the conditions exist, repeat the bleeding procedure.
Bosch® III Anti-lock Brake System
  1. Turn the ignition switch OFF.
  2. Using at least 50 lbs. pressure on the brake pedal, depress the pedal at least 25 times; a noticeable change in pedal pressure will be noticed when the accumulator is discharged.
  3. Check and/or refill the reservoir to the full mark.
  4. Using a transparent vinyl hose, connect it to a pump bleeder screw and insert the other end in a beaker 1?2 full of clean brake fluid.
  5. Loosen the bleeder screw 1?2 - 3?4 turn. Turn the ignition switch ON; the pump should run forcing fluid from the hose. When the fluid becomes bubble-free, turn the ignition switch OFF, tighten the bleeder screw.
  6. Move the transparent vinyl hose to the hydraulic unit bleeder screw. Loosen the bleeder screw 1?2 - 3?4 turn. Turn the ignition switch ON; the pump should run forcing fluid from the hose. When the fluid becomes bubble-free, turn the ignition switch OFF, tighten the bleeder screw.
  7. Disconnect the bleeder hose.
  8. Turn the ignition switch ON and allow the hydraulic unit to charge; the pump should turn OFF after 30 seconds.
Bosch® 2U Anti-lock Brake System
  1. Turn the ignition switch OFF.
  2. Using at least 50 lbs. pressure on the brake pedal, depress the pedal at least 25 times; a noticeable change in pedal pressure will be noticed when the accumulator is discharged.
  3. Check and/or refill the reservoir to the full mark.
  4. Using a transparent vinyl hose, connect it to a pump bleeder screw and insert the other end in a beaker 1?2 full of clean brake fluid.
  5. Loosen the bleeder screw 1?2 - 3?4 turn. Turn the ignition switch ON; the pump should run forcing fluid from the hose. When the fluid becomes bubble-free, turn the ignition switch OFF, tighten the bleeder screw.
  6. Move the transparent vinyl hose to the hydraulic unit bleeder screw. Loosen the bleeder screw 1?2 - 3?4 turn. Turn the ignition switch ON; the pump should run forcing fluid from the hose. When the fluid becomes bubble-free, turn the ignition switch OFF, tighten the bleeder screw.
  7. Disconnect the bleeder hose.
  8. Turn the ignition switch ON and allow the hydraulic unit to charge; the pump should turn OFF after 30 seconds.

94 caddy sedan deville 4.9 transmisson wont engage into any gears

If you are sure the fluid level is full, the filter could be leaking pressure or not allowing fluid to pass thru. There may not be enough fluid in the valve body to make the transmission function.

94 4x4 3.0 v6 3vze 4runner ...power steering pump recently replaced by myself ,yet still does not work when braking hard or not accelerating ...is it possible it just needs a fluid flush or maybe an air...

It would appear that there is air in it. Try turning all the way left, and then all the way right a few times, and see if that helps. That should be all you need to do if it really is air. Let me know if it persists.

After I changed the brake pads and brake caliper on a 1998 Cadillac Deville the Traction Control and the ABS light came on.

Hi and welcome to FixYa!

This is normal after replacing the brake pads. You can take it to any shop that has a device to erase the log on the dash. This is computer related and needs to be removed by a scan tool.

Hope this helps and thank you for using FixYa!

What else do i need for tune up on 99 cadillac deville besides plugs and wires

There isn't much to a tuneup now days, I wouldn't even bother with plugs and wires unless it needed it. The basic tune up is an oil change, air filter, check all fluids, brake pads, hoses, any thing that needs attention. I don't think I have changed plugs in 10 years, or wires for that matter. And I am driving a 94. Hope this helps.

Brakes lines rusted on a 97 cadillac deville

Metal brake lines rust with age, become potted & leak fluid. Replace with copper pipe, is only marginally more expensive, the labour to replace will be the same but copper wont rust, so future cost saving & safety. Job is easy enough to do yourself, unscrew where it joins master cylinder, then follow line back, clipping it out from any securing clips, unscrew other end, coil up & take to motorfactors, ask them to make a copper brakepipe exactly like your old one, dont worry if you snap pipe during removal, take all bits with you so correct length can be gauged. Copper is very flexible & can be bent to shape when you refit. Make sure you have new brake fluid to bleed your system with after replacement.
Have fun.

Digital dash

Work the headlight switch round and round first. That's the dimming feature of the dash lights. Maybe they messed with it. Digital dashes have problems especially at that age of car. If nothing works see about a used one from a salvage yard

Need 2 change brakes on 94 cadillac deville

Brakes are something that most drivers should not attempt mostly because when you step ,on the brakes you want to stop. You don't say if you have caiper brakes all around or just on the front. I have worked on brakejobs for quite a few years and always do the calipers too. repairs are expensive nowadays as with most repair shops. most shops charge one for things that they don't change so it is expensive. To do a brake job properly one needs specialized tools and know how.

Clutch pedal drops when I apply brake, so can't change gears

I suppose your clutch master or slave cylinder is leaking. You must keep an eye on the brake flui leven and drive to a workshop for a check asap. You can use DOT3 brake fluid.
