Brake flushes are a routine maintenance procedure that should be performed on all brake systems at least once a year. By understanding how much fluid is needed for a brake flush and when it should be done, you can keep your brakes in good working order.
What is a brake flush?
A brake flush is a cleaning procedure that is typically performed on a motorcycle or car’s brake system. It is performed when the brake fluid appears to be dirty or low on fluid. A brake flush can also be performed as a preventive measure in order to keep the brake system in good condition.
How to do a brake flush
If your brakes are acting up, it may be time for a brake flush. A brake flush is a simple procedure that cleans and lubricates your brakes. Here’s how to do it:
1. Park your car on a level surface with the emergency brake off.
2. Remove the wheel and tire.
3. Loosen the brake pads if they’re bound together by clips or springs. If the pads are not bound, just loosen them enough so they can move freely in their holders. (Be careful not to overtighten the pads.)
4. Pour a pot of boiling water onto the parking lot, making sure that it doesn’t splash onto your car.
5. Place the brake calipers and discs into the boiling water and let them sit for about 5 minutes. (Don’t let them touch anything else in the pot!) The calipers will pop out of the water after about 5 minutes, but don’t worry—the discs will stay in until you’re done.
6. Remove the calipers and discs from the water and dry them off with a cloth or paper towel. If there’s still gunk on them, use a clean rag or cloth
Why you should do a brake flush
If your car has been sitting for a while, the brake fluid can become thick and difficult to flush. Brake flush is important because it helps to remove built-up debris and sediment from the braking system.
To do a brake flush, you’ll need:
-A container that will hold at least 2 gallons of fluid (a large bucket is perfect)
-A garden hose with a shut-off nozzle
-A plunger or vacuum cleaner with a hose attachment
-Rags or a old T-shirt to catch the fluid
-Brake fluid (any type will do, but DOT 3 is recommended)
-A funnel
-Tape measure or ruler
1. Fill the container with enough fluid to cover the brake pads and reservoir. Add enough fluid so that the level reaches the top of the pads. If your car has ABS, add more fluid until the level reaches the ABS sensor housing. Be sure to include any extra fluid that may have been drawn up by the vacuum cleaner when you removed the cap.
2. Secure the container in place with tape or clamps. Invert it so that the open end is down and connect the garden hose
What to expect after doing a brake flush
After doing a brake flush, you may experience the following:
-A decrease in brake pedal pressure
-An increase in brake squeal and feel
-A reduction in stopping distance
