ITEQ Brake Fluid Liquid Tester Pen with 5 LED Indicators, Calibrated For DOT3 DOT4 Brake Fluid

Product Information

The primary brake tester must be used unless the vehicle is unsuitable due to its drive configuration, transmission type or braking system. If this is the case, a full or partial decelerometer test may be appropriate. You should consider any additional information from the vehicle manufacturer. i) the braking effort from any wheel is less than 70% of the maximum effort recorded from the other wheel on the same axle. Or in the case of testing on the road, the vehicle deviates excessively from a straight line. For non-automated roller brake testers the brake test weight must be obtained from a brake data chart or other reliable source. As soon as the wheels are on the plate high friction braking surfaces, gradually apply the secondary brake, keeping any ‘hold-on’ button or trigger disengaged the whole time, until maximum effort is achieved. Evaluate the brake fluid's boiling point with an electronic tester. New DOT 3 specification brake fluid is to have a dry boiling point of 401 degrees Fahrenheit (205 degrees Celsius) and a wet boiling point of 284 degrees (140 degrees Celsius), while DOT 4 fluid is to boil at 446 degrees (230 degrees Celsius) dry and 311 degrees (155 degrees Celsius) wet. The lower the point at which the brake fluid boils, the less effective it is.

If the metal brake pipes have surface dirt that needs to be removed before it’s possible to assess their condition, you can lightly scrape the pipe with a specialist brake pipe corrosion tool or the corrosion assessment tool ‘spade end’.

If you are not sure the type of brake fluid your vehicle uses by simply looking at the brake fluid color, you can use this tester, which would work just fine. It uses a 9V battery that is sold separately. It powers up and lets the user audibly know that it is ready. In cases where the required brake efficiency is only just met, but the tester knows that a higher performance figure is normally obtained for the vehicle type, the vehicle presenter should be informed.

A vehicle with an ULW up to and including 3,050kg, with a reservoir coupled direct to the induction manifold or a reservoir integral in a servo unit, does not need to be fitted with a warning device. At first glance, there’s little difference between Sealey’s VS0274 and our test-winning Laser. In fact, they were equally accurate. For most vehicles, the time to change brake fluid is usually indicated in the owner’s manual, but if you are not sure, use thebest brake fluid testerto determine if it is already time to drain the brake fluid. Your safety and that of other motorists’ matters at all times; thus, the braking system should never be taken for granted. You must inspect any additional braking device fitted, such as an electric or fluid retarder or an exhaust brake.

When testing ABS equipped vehicles, the road wheels that are lifted off the ground should not be allowed to rotate when the ignition is on. This can cause the ABS system to indicate a fault which may require specialist equipment to rectify. You’ll see low and maximum markers – if the fluid is below the low marker, you need to top it up as soon as possible and arrange for your brakes to be inspected. Not tested” or “Unable to be tested” must only be used where it becomes apparent during the test that the particular item cannot be tested, and this could not have been identified prior to starting the test. The reason for selecting the failure must be included in the additional information box. DefectThese vehicles must instead meet the secondary brake test requirements. For details see Section 1.3.1 and 1.3.2. To test accuracy, we put 100ml of DOT4 brake fluid into a jug for our first measurement, where moisture content should be close to zero. We then repeated the tests with 2.5ml, then 5ml, of water in the 100ml to see how the units responded.

You must inspect the warning lamp operation on vehicles with an electronically controlled braking system. Defect Submersible Pumps - Fountain & Pond Miscellaneous and Transfer Pumps Pump Accessories Pump Controllers & Switches Hose Hose Clips Couplers, Valves & Filters Washdown Pump Kits Before carrying out a decelerometer test on the public highway, testers must ensure they are suitably qualified to drive the vehicle and are familiar with the controls. If a vehicle has special controls, such as in disability vehicles, the vehicle presenter should be allowed to drive during the test if he/she wishes. Calculating brake imbalanceSome vehicles with full power hydraulic braking systems will illuminate the low-pressure warning light as soon as the ignition is switched on. It is not a defect unless the warning light stays on after the engine has been started. Defect For vehicle category definitions see the ‘Abbreviations and definitions’ in the ‘Introduction’. Vehicle type These machines are type approved and should not be rejected for design features that prevent them from meeting the stated requirements.
