0:04 – SUPER: MASTER CYLINDER BENCH BLEED
0:08 – VO: OK what we’re going to do today is bench bleed a master cylinder. There are two methods of bench bleeding a master cylinder. This version is plugging the ports and cycling the piston.
0:20 – VO: First thing you want to do is fill the reservoir with brake fluid. Allow the master cylinder to gravity bleed, then plug the ports.
0:40 – VO: Once you plug the ports, you can cycle the piston within the master cylinder. You want to make sure you use the appropriate tool. Don’t use a tool that’s a screwdriver or sharp on the end. If it slips off the piston, you could damage the bore.
0:55 – VO: We’ll cycle the piston now, and you’ll see bubbles will raise within the master cylinder. Once all those bubbles are gone, you’ll find that you cannot push in the piston anymore. At this point you’re ready to install the master cylinder.
1:19 – VO: The second method of bench bleeding is using recirculation tubes. Fill the master cylinder up, install the tubes, make sure they’re submerged in brake fluid. The next thing you want to do is, once again, make sure you use the proper tool so you don’t damage the bore. You don’t want a sharp object in case this slips off and you damage the bore.
1:41 – VO: Install the tool and cycle the piston. Continue to cycle the piston until all the air bubbles are gone.
2:30 – VO: OK you’re ready to install the master.

0:03 – SUPER: NAPA BRAKES; ISOLATION TEST
0:08 – VO: One of the biggest challenges in the repair business is diagnosing a low spongy brake pedal. This is very esay to accomplish by doing what’s called an isolation test. An isolation test consists of clamping off all the rubber hoses on the vehicle, whether there’s three or four, and evaluating the brake pedal.
0:25 – VO: You want to use the appropriate tools as you see here on the bench. You want to use a tool that will not flatten out the brake hose and has a radius in this area. What you do not want to use is a pair of vise grips. Let’s install a clamp on a wheel here and we’ll diagnose it.
0:41 – VO: OK now we’re gonna clamp off this brake hose in this area. Next you want to clamp off the other three wheels.
0:53 – VO: Now that we have all the hoses clamped off, the next step would be, start the vehicle and evaluate the pedal height. Could you start the vehicle please?
1:06 – VO: How’s that pedal feel?
1:10 – VO: That feels great.
1:11 – VO: OK so we have a good brake pedal right now, so that tells us that there’s a problem in the vehicle below the clamps. The next step would be to remove one clamp at a time. So what we’ll do is remove the clamp.
1:27 – VO: Now we’ll start the vehicle again and evaluate it. Would you start the vehicle please?
1:34 – VO: How’s that pedal feel?
1:38 – VO: Still good.
1:40 – VO: OK. Next step would be to put the hose clamp back on that particular hose and go to the next wheel.
1:50 – VO: OK now we’re going to take off the clamp on this next wheel here and evaluate it. Remove the clamp, let’s start it up and evaluate.
2:03 – VO: How’s that pedal feel?
2:06 – VO: Pedal’s soft.
