Kit contains a complete set of fittings and gauges for pressure testing ABS and conventional brake systems on Chrysler Ford GM Jeep and import vehicles Two 0-3000 PSI gauges 16 adapter fittings, two Bosch ABS adapters, one Teves/Delco Powermaster III adapter, one Ford Teves adapter, one 90 degree elbow fitting and one 45 degree elbow fitting and bleeder I was in a situation the other day where I was getting ready to do a brake project on the TJ and I wanted some accurate before and after numbers to see what kind of change might occur. A good friend was kind enough to loan me his brake line pressure test kit. Too many of us have read those on-line comments that go something like "I put the XYZ brake thing on my Jeep and the braking was much better....I could feel the difference, no doubt about it." I've been guilty of it and I am sure many of you have as well. So, I decided to gather some real numbers so I didn't have rely on my....well, what ever it is you rely on when you make those kind of statements.
If you are like me, you may need to use one of these once or twice in your life (or not). I can't justify buying something that will see that kind of use. However, if you want the real numbers, then it is hard to live without it. The kit comes with a pair of 3000 PSI gauges and a variety of adapters that allow it to be hooked up to just about any brake line fitting
Use is quite simple. I wanted to check my the line pressure at my front calipers. To do so, you start by removing the bleeder valve from the caliper. Find the appropriate adapter in the kit and screw it into the caliper. The gauge is connected to a short length of high pressure hose with a fitting that will connect to the adapter you just put in the caliper. A bleeder valve is located at the base of the gauge which allows you to bleed the air from the hose.
The gauge as one of those pointers on it that allows it to retain the highest line pressure.
You can reset it to zero at any time in order to record a new peak pressure.
With your buddy in the driver's seat, bleed the air from the test hose.
Reset the pointer to zero and have your friend push the brake pedal. Read the numbers and you are done. When done, remove the hose and the adapter from your caliper and reinstall the caliper bleed valve. You will have to bleed your brakes since you have opened the system but the way I see it, this gives you a good reason to get a fresh container of brake fluid to flush out the old junk in your lines (you know, the stuff that always comes out darker than the new stuff you add to the master cylinder).
If you are having problems or concerns with the disc brakes in your vehicle, you can perform a hydraulic pressure test to gauge the hydraulic pressure created by the master cylinder in your car . This will give you a good indication if enough pressure is being created by the hydraulic pump, or, in some cases, it will let you know if too much pressure is being supplied to the brake calipers in your car. So, here is a simple step by step guide that will show you how to test the hydraulic pressure in your car's brake system.
Step 1 - Obtain a Brake Pressure Test Kit If you don't already have a hydraulic brake pressure test kit, you'll need to buy one at a local auto parts store or online.
When shopping for a test kit, choose one that has multiple adapter fittings to make sure it will work with your car.
Step 2 - Jack Up the Vehicle Jack up the car with a car jack and place it on jack stands so that you can work under the vehicle.
Step 3 - Remove Tires and Wheels Use the lug wrench to remove the tires and wheels from the vehicle.
Step 4 - Remove Bleeder Valve Screw Locate the bleeder valve screw on your brake caliper. It may be a screw or small bolt, so use the appropriate tool to remove it.
Step 5 - Attach Pressure Test Gauge to Caliper Bleeder Valve Once you have removed the bleeder valve screw, find the correct adapter fitting and attach it to the pressure gauge. Then, connect the pressure gauge to the bleeder valve stem on your brake caliper.
Step 6 - Apply Pressure on Brake Pedal Have your assistant step inside the vehicle begin applying pressure to the brake pedal.
Step 7 - Read Pressure Test Results Once your assistant places pressure on the brake pedal, you should notice that the pressure indicator on the gauge begins to rise. Most pressure gauges will have a highest pressure point indicator, which will allow you to keep track of the highest pressure level of the hydraulic fluid moving through your brake system. This is the number you can use to compare pressure levels in your car owner's manual to determine if your car's hydraulic brake pressure is at an appropriate level.
Step 8 - Remove Pressure Test Gauge Disconnect the pressure gauge from the brake caliper bleeder valve.
Step 9 - Bleed the Brake System Since you have opened the hydraulic brake system in the vehicle, you'll need to bleed the brakes. Therefore, have your friend apply pressure to the brake pedals while the bleeder valve screw is open. Once you have completed bleeding the brakes, close the bleeder valve screw.
Step 10 - Add Brake Fluid Fill the brake fluid reservoir in your vehicle with DOT 4 specification brake fluid.
Step 11 - Test the Brakes Have your friend again test the brake pedal to see if the pedal feels spongy. If it does, you will need to bleed the brakes again.
Step 12 - Replace Tires and Wheels Reinstall the tires and wheels, and tighten with the lug wrench.
Step 13 - Lower the Vehicle
