i have 66 with front discs and power asst. i bled the lines and have no air what so ever, untill i touch the break pedal. once i touch the pedal air gets into the lines again. do i have to wait to do this untill i have the vac set up or what!? help im freakin out.

 

Did you bench bleed the master cylinder?

 

is your bleader pointing up or down? if its down, it's pocketing the air and its way harder to bleed them that way.

 

yeah i bench blead it and no air at all, and my bleeder is iup. I tried everything but air keeps comming after i pump it...any sugestions

 

You must have a leak somsplace or the master is toast.

 

Tony...does the brake pedal go down slowly with your foot on it after you pump/bleed the brakes? If so, might be bad master cylinder...Drums on back? Might be wheel cylinder leakage..

 

make sure u do it like this! Back
Bleeding the Brakes

BLEEDING THE BRAKES





Bleeding the brakes requires a properly sized box wrench for the bleeder and the clear plastic bleed hose provided with your system. Good quality, non-silicone fluid is also a must. Baer Brakes has tested a wide variety of fluids and strongly recommends Performance Friction’s Z-Rated fluid #90016 for street and occasional track use (with Motorcraft PM1 our backup suggestion for this same duty). These two have been proven to be more effective than fluids that are often many times more expensive. For racing, Baer recommends and uses only Castrol SRF. Baer stocks and sells both the Performance Friction Z-Rated and Castrol SRF.



Always remember, good to excellent brakes or fluid do not function without

adequate cooling. In fact, the more serious your brake system, the more attention that needs to be directed to proper ducting, as they will generate more heat due to

increased capacity.



BLEEDING BRAKES IS NOT DONE WITH PRESSURE, IT IS PURELY A FUNCTION OF MOVING FLUID THROUGH THE SYSTEM. THE OBJECT IS TO DISPLACE AIR, NOT TO SEE HOW FAR FLUID CAN BE SHOT OUT OF THE CALIPER!


Proper Bleeding Technique


Enlist someone who will help you bleed the brakes. Make sure they also read

these instructions carefully (so they understand the goal).



1. For systems which are essentially dry front and rear, start by filling the

master cylinder with proper fluid. Pour slowly so as not to aerate the fluid.

2. Next, move to the first caliper, attach the clear plastic bleed hose to the

bleeder and open it. Hold the hose upright so that you can monitor the escape

of air bubbles. VERY SLOWLY stroke the brake pedal by hand or foot until

fluid comes out. Now close the bleeder.

3. ACTUAL BLEEDING SEQUENCE:

A. Have your partner very slowly, with modest pressure (approximately 25-30

lbs.f.), stroke the pedal ONE TIME until hydraulic resistance is

encountered. Ask your partner to hold at this point with the same modest

and even pressure and notify you that he is “holding.�

B. Open the bleeder, letting the pedal go to the floor or until it stops, using

the same modest level of pressure, then close the bleeder again. Notify your

partner “the system is sealed.� He can then slowly release pedal pressure.

4. Repeat the BLEEDING SEQUENCE (never stroke the pedal more than one

time) until all signs of air are purged (no bubbles) from fluid. IMPORTANT

NOTE: DO NOT LET THE MASTER CYLINDER RUN DRY! Be sure to check

the fluid level after every third bleeding sequence or sooner if reservoir

volume is very small.

5. Before moving to the next caliper, take a small block of wood or a plastic

hammer and carefully tap the caliper to dislodge any additional air bubbles

that may be trapped. Then bleed one last time.

6. Move to the next caliper and repeat the procedures previously outlined.

Continue until all calipers have been bleed.



Before re-installing wheels and placing the car on the ground, we recommend you

carefully wipe clean all caliper surfaces, hose joints and fittings, making sure

they are all dry and free from seepage. If not, inspect and tighten appropriately. Spray all rotor surfaces with Brake Klean® or a similar product to remove all dirt and oils from your hands that may have been transferred to the rotor during assembly. Also remember to remove the nut that has been holding

rotor in place before attempting to re-install the wheel.



For street use, as with any time you open the brake system, it may be advisable

to repeat the bleeding procedure after driving the vehicle for a day, as driving

the car may dislodge some additional air bubbles. For competition cars, we

recommend repeating this procedure directly after at least the first two

sessions the car is on track and at the beginning of each race weekend

thereafter.



Even if your pedal is high and firm and additional bleeding is deemed

unnecessary, always inspect the calipers, hoses and fittings after the first

outing for signs of any fluid seepage and correct immediately.

 

thanks guys ive had two master cylinders and both do the same so i know they are in working order, I was not bleeding correctly as what the post said so i am going to try that. If that does not work I need to find myself a leak! thanks for the help guys ill let you know how it goes
