Welcome today's video clinic, changing brake fluid. So much of the time we talk about what makes a ve That's right, changing brake fluid can be very controversial. Manufactured and manufactured, they disagree as to exactly when it should be done, but we know it should be done because brake fluid can get contaminated, it absorbs moisture, and it can cause fading, brake fluid boiling, and it can even destroy expensive ABS components. That's right, and t You got about an hour, t Let's take a look at the t You'll want to look at your owner's manual or check with an advanced auto parts team member to find out if you'll need . 3 or . 4 brake fluid. A lot of great options out there for brake fluid folks. Today we're going to use the valvelyne synthetic brake fluid, w 3 and . 4 standards, great in all ABS systems. Another t You can either use a one man brake bleeder Or you can use another really nifty tool, both available in advanced auto parts. We really like this, it's a vacu We're going to suction the old fluid out of the master cylinder as well as bleed the lines and fill the lines with a new brake fluid using the first step is to put the canister on the p T You need to make sure you get the tube all the way down into the bottom of the reservoir. There's usually a primary and secondary reservoir. We make sure the tube is all the way down in to pick up all the fluid possible. You can see how quickly the reservoir fills up and look how brown t You can tell that it's old worn brake fluid. I Great idea. The fluid doesn't get all over the paint and t Now get yourself a nice clean rag and try to get out as much as the dirt as you can around the inside of the reservoir and the outside of the neck so that we have a nice clean place to start with. So working as quickly as possible so we can get that lid back on the master cylinder, we're going to go ahead and add new synthetic fluid. Just fill it to the line level where it says full. Almost all master cylinders show you where the full is. Okay, it's full Brian and I'm going to put the cap on as quickly as possible to keep the air out. We're at the back of the ve We've actually got all four wheels removed so you can see what we're doing. This particular vehicle has dr So on the back of the backing plate you can see the bleeder valve. I pull the rubber boot off and expose the bleeder valve. So we're using the same vacu It simply connects to the back of the bleeder valve We take in t Jim has given us a good pedal full of pressure. Loosen the bleeder valve. You can see it coming out the line along the few air bubbles. T You can see the old contaminated fluid coming out. Give it about 15 or 20 p Go ahead and tighten your bleeder valve back up and we've got to add some fluid to the master cylinder reservoir up front now and we'll do t Well I've completed the passenger side front of the ve Now we're working on the driver side front w You can see the brake line as it travels down and comes into the caliper and again we're attached to the bleeder valve. We go ahead and crack open the bleeder valve and drain the rest of the contaminated fluid out of that line. P Watch for the air bubbles to dissipate. There you go. You can see the golden brown solid line in the tubing coming off the bleeder valve. That means we've got all the new brake fluid filled into the caliper and no air bubbles. We're just about done. We're going top off the master cylinder and we'll be ready for a test drive. It's a good idea to take time to check the brake pads and the rotors w Now in some ve After you p And the ABS light should go off after the car ignition is turned off and then on again. If it doesn't go off unhook your battery the negative terminal so the computer will reset. So we spent about an hour changing the brake fluid on t We had the right tools for the job we got a great pedal and I'm looking forward to the test drive. That's right. So the next time you're changing your brake pads go ahead and spend the extra hour and change your brake fluid. It's a great investment in your safety.
