How to Repair Buick Brakes Guide
Your vehicle may have a common problem of low brake fluid that is caused by air getting into the lines. Air can easily make its way to get to the lines as the system is not made air tight at all. This causes a spongy brake pedal. To deal with this problem you have to be acquainted with the procedure letting you know on how to repair Buick brakes.
Things you’ll need:
To repair Buick brakes, you will need the following thing:
- Power brake bleeder kit (includes tubing)
- 2 bottles of brake fluid
- 10mm box end wrench
First thing to do is to open the hood and then join the power bleeder with the brake master cylinder. Now take away the brake master cylinder cap through pressing down on the cap and turning it in anticlockwise direction. Put screw on the cap that is connected to the power brake bleeder to master cylinder reservoir’s top. Keep in mid that this power bleeder has its own reservoir tank and a hand pump on its top plus a hose that usually runs from the tank to the master cylinder
Now take away the cap from the power brake bleeder reservoir tank and then use brake fluid to fill it. After that put back the cap and tighten it.
To increase pressure in the reservoir tank, you have to force the handle on the top of the bleeder reservoir tank
Now put the 10mm box end wrench above the bleeder valve on the brake caliper and begin with the correct rear wheel. To get to the valve (at the bottom of the brake caliper) you have to reach at the back of the wheel.
Now it is time to put the 1/4-inch bleeder tubing above the bleeder valve’s end. Confirm that it is safe on the valve.
Next you have to put the other end of the hose into a container.
Open the bleeder valve and let the air to come in the lines. Several brake fluid will also be barred.
When you see that the pressure has been fully released then, close the valve.
To build pressure, again force the handle on power bleeder’s top. After that; perform step 7 and 8 again. Carry on this procedure until air completely comes out of the lines at that wheel and afterward go to the left rear wheel and bleed that side. By doing the same process with left rear go to the right front and then left front sequentially.
After you have finished with bleeding all four wheels of your vehicle and have put the master cylinder cap back onto the master cylinder’s top now test out the pedal pressure. Verify that the brake fluid (in the master cylinder) is quite between the upper and lower marks given on the reservoir tank.
