“On cars that have sat for a really long time, I’ve seen a white paste form inside the system,” Hines adds. Pushing a brake piston fully out of its housing will cause a mess, and it’s not exactly easy to put back in. This might seem obvious to some, but it’s still something you should keep in mind if you happen to be changing pads at the time. “Don’t ever push on the brake pedal if you don’t have the brake pads installed and mounted on the rotor, because you’ll pop the pistons out,” Hines says. Doing so will ensure all of the air and debris trapped in the system is removed properly. “If you’re really doing a thorough job, and especially if you’re taking your car on the track, you’ll want to do the inside and the outside,” Hines says. Some cars have brake calipers that feature more than one bleeder screw, one on the inside and another on the outside. Once the fluid comes out clear on all four corners, congratulations, you’ve bled your brakes. We recommend going passenger-side rear ⇒ driver-side rear ⇒ passenger-side front ⇒ driver-side front. Once it does, you can move on to the next caliper. Repeat these steps until the fluid starts to come out clean.

Crack open the screw again, and more fluid should come out.
Aaron BrownĪfter fluid stops flowing, close the bleeder screw and either pump up the pressure bleeder or instruct your assistant to pump up the brake pedal. You don’t want to snap it off inside the caliper. When loosening the bleeder screw, try to be delicate. Hook up the tool you’re using to catch the fluid to the bleeder screw, then make sure there’s adequate pressure going to the brakes (either with the pressure bleeder primed or your buddy holding the brake pedal down). Going to the back of the car ensures the system will be fully flushed, with no potential for old fluid to be caught in the system. “Always start at the caliper furthest away from the master cylinder,” Hines tells us. Now, you can finally begin the bleeding process. Forgetting to do this could introduce air into the system. As you bleed the brakes, fluid will come out, so you’ll have to periodically top it off. If you’re not using a power bleeder, make sure to keep an eye on the fluid level in your brake master cylinder. But if that’s the case, you’ll need another person to help, as the steps are a bit different. If you’d rather not spend the money on a pressure bleeder for a simple brake fluid job, we understand. All you have to do is fill it with new fluid, connect it to your master cylinder, and pump it up with either a handheld lever or, if your bleeder has it, a compressed air connection. Having a pressure bleeder means you don’t need someone in the driver’s seat manually pumping the pedal to generate enough pressure to push out the old fluid. Alternatively, you can buy something made for the job: If you’re on a budget you can use an old water bottle. You should also have a clear tube that can mount to the bleed screw going to a clear container to catch the old fluid. Keep in mind the size of the screws may be different on front and rear calipers. Don’t cheap out on the jackstands!īe sure to have a wrench to open and close the bleed screw on your calipers. If you don’t have an automotive lift-and you likely don’t-you’ll need a couple of jackstands to get the car in the air so you can get the wheels off to access the bleed screws. Having the Right Tools for the JobĪt minimum, you’ll need a couple of basic tools to swap out your fluid. In some instances, you can find this information printed on your brake fluid reservoir fill cap, located in the engine bay.
Brake bleeding kits manual#
Refer to your owner’s manual to see which type of fluid you should buy. “Get what’s applicable to your car or what’s already in the system,” he says. There are many different kinds of brake fluid, and your car’s braking system was designed to work with a specific type. “Make sure you use the right brake fluid,” Hines says. Before you get started on actually flushing your brakes, first confirm you have the right product for your car.
