SOURCE: 1986 Ford E-150 Brake line problem

when you bleed the brakes start from the p/s rear then d/s and so on make sure to crack the bleed screw and not the bleed nut also check the brake booster for correct movement thats what opens the pistons on the master cylinder

SOURCE: Having trouble bleeding brake lines

Hi. First you need to gravity bleed the left caliper or wheel cylinder, if you replaced a large section of line it will take longer to bleed. If you ran it low on brake fluid until the brake pedal was on the floor, then you may have damaged the master cylinder, and will need to replace it in order to bleed the brakes.

Having trouble bleeding brakes for 2009 jeep wrangle 4wh drive when car is off the brakes seem fine , but when the car is on the brake pedal goes almost to the floor


Because when you start it the brake booster will start working, start bleed on wheel farthest from master cylinder and work closer, one at a time pump up and bleed each line at least once after you don't see air anymore...

My front break is leaking from a warn spot on the hose attached to the caliper.


Replace the brake line, you can pick up the replacement line at the GM Dealer, Napa, or Auto Zone and they can give you the step by step instructions to replacing it with common tools. Once the line has been replaced, make sure you buy some brake fluid to be able to bleed the brake system to ensure there is no air in the system.

Thank you for using fixya and stay safe.

I replaced the thermastat but now am having trouble getting the heat to stay hot and bleed the air out of the system. Why would this happen?


because GM messed up by having hoses above the bleeder. jack the passengers side up and bleed from bleeder above water pump. might need done multiple times

2002 avalanche 1500 Left rear brake assembly over heating. Just replaced rotor and shoes both sides, only having trouble on left rear.


Check the flexible hose between the solid brake line and the hydraulic braking actuator (since you said "shoes" this actuator is the wheel cylinder.)

There's trash of some sort in that flexible hose...I can guarantee it.
GM is bad about this problem.

Hope this helps ya out...

I am having trouble bleeding my brakes on a ford courier there is no pedal there when i have bled the brakes and i have also tryed changing the master cylinder and it is the same


Start by bleeding master cylinder, will take two to do this, have some pump the brake paddle about ten time every time, have them pump it and hold it down while you open brake line when paddle goes to floor close and pump again ( one of the brake lines at the master cylinder ), keep doing that till no more air comes out, then do the other brake line at master cylinder again till no more air comes out, keep an eye on master cylinder that it don't go low on brake fluid or you will have to start all over again, how go to right rear wheel and bleed till no more air comes out ( have them pump brake paddle and hold while you open and close bleeder valve, do not let them release brake paddle till you have close bleeder valve, keep doing that till no more air comes out, then go to right rear, then left rear, from there right front and last left front.Hope this was very helpful, good luck.

What service does an 04 pontiac needs at at 80k?


gm coolant requires replacement at 5yrs/100,000 miles. rec having cooling system flushed. other then that a general inspection should be all thats required at this interval inspection should include brake linings, fluid lvls, air filter, tires, fluid leaks ect. although there may not be manufacturer requirements for transmission fluid and filter change may want to consider having it done, also fuel system service with injector flush is very benificial to fuel mileage and restoring engine power. gm does NOT ever recommend engine crankcase flushes that some service shops sell. spark plugs in these engines do not require replacing until 100k miles unless causing engine to run rough

No brakes after changing brake caliper & bleeding system


Sounds like you still have air in your brake lines. Make sure all your brake lines are tight. Then bleed again. Bleed the trouble side first, meaning right side, then go to front left, back left then back right, make sure that your brake fluid is also full
