How do you bleed the brakes on a Pontiac Grand Am?
Open the bleeder valve on the caliper and have an assistant press on the brake pedal inside the Jeep. Look for a mixture of air and fluid to come out of the valve. Once all the air is purged and the fluid runs cleanly from the valve, close the screw and remove the tube. Repeat the process for all four brakes.
How do you bleed air out of front brakes?
If your vehicle has squishy-feeling brakes, the way to get the air out of the lines is to bleed the brakes. To do the job, you need either a brake bleeder wrench or a combination wrench that fits the bleeder nozzle on your vehicle, a can of the proper brake fluid, a clean glass jar, and a friend.

How do you fix spongy brakes after bleeding?
If the brakes are soft or spongy, this is a good time to change or flush the brake fluid. Flushing the brake fluid, commonly called bleeding the brakes, gets rid of the air. (Bleeding the brakes uses fluid to push air out of the brake system.) Over time, brake fluid absorbs moisture.
Where do you Bleed the brake lines on a Pontiac Grand Prix?
It is recommended that you begin bleeding the brakes lines at the wheel farthest from the master brake cylinder and then working your way towards the brake cylinder.
