Tip & How-To about Miscellaneous
Brakes overheating: The heat of the system causes the air in the system to expand more than brake fluid and it actually applies pressure to the brakes as you warm up the vehicle. The more you drive the worse it gets and sometimes will cause a wheel to lock-up.
If you replaced the master cylinder make sure you bench bleed it before installation or at least prior to connecting the brake lines in the vehicle.
To properly flush or bleed the brake system:
During this entire process, do not let the master cylinder reach the bottom or you have to start over. Check before each attempt to bleed the brakes. Refill at the 1/2 way mark or close.
Before starting, you should cautiously fill the master cylinder to the full amount and re-install the lid on the brake fluid and the master cylinder to limit splashing (air gets into the fluid) during the bleeding operation. This is a 2 person operation.
First, to get all of the air out you must start at the wheel farthest from the master cylinder, the Right Rear! After breaking the bleeder valve loose but still not letting brake fluid drain,,, have your assistant pump the brakes until tight as possible and then hold the pedal to the floor until the fluid has been bled from the first location. Follow the pedal to the floor as pressure is released and DON'T release the brake pedal until you have made sure the bleeder valve is closed. Repeat this until you have no air at all and clean fluid. Now, do the next wheel. Left Rear! Next the Right Front, and finally the Left Front. By following this method you will have eliminated all of the air from the brake system as long as you don't have any leaks.
