The Life and Adventures of Martin Chuzzlewit (commonly known as Martin Chuzzlewit) is a novel by Charles Dickens, considered the last of his picaresque novels.It was originally serialised between 1842 and 1844. A native app allows you to use the operating system's built-in interactions and UI allowing for a more engaging and immersive experience. Unlike other app builders Taply provides a complete native app. A mix of the charming, modern, and tried and true.
The original brake test meter
In production for almost 100 years
Hand-made precision instrument
Measures deceleration and stopping distance
Portable
DVSA-approved
Easy to use
For Vehicle Classes 3, 4, 5 & 7
Available with floor block or clamp
Available with scale in Feet or Metres
The Tapley meter is the most recognised international standard decelerometer, and as such is trusted by many leading government authorities around the world to set local brake testing standards. Results of Tapley meter tests are accepted as evidence of braking efficiency in Courts of Law throughout the world.
For new customers we recommend that the Bowmonk Brakemeter / Dynometer is ordered instead, but for existing customers the Tapley Brake Test Meter is still available to order with a scale reading in either Metric or Imperial for stopping distance. G force is always shown in %G. The vehicle being tested must be driven at a speed of at least 15 mph (20 mph recommended).
A choice of two mounting mechanisms is available - a floor block or a clamp. All floor block mounting types are supplied with wooden boxes, while clamp mounting types are supplied with carry cases. Please refer to the 'Part Codes' tab above for the various Tapley Meter models.

Latex Paint Loosener If the paint causing the brush stiffness is latex-based, soak the brush in hot water or run the bristles under hot tap water, flexing the brush back and forth against your hand a bit to help loosen the paint's grip on the bristles. Clean dried paint brush. Soak the brush with hardened paint in vinegar for an hour. If the bristles don’t bend, soak for an additional hour. If it needs more loosening after two hours, submerge the head of the brush in vinegar in a pot, place the pot on a stove and bring to a boil. Having purged your paint brush of wet paint, you're ready to rid it of any caked-on dry paint as well. If the dried paint is oil-based, begin this step by pouring turpentine onto the stained bristles. Alternatively, if the dried paint is water-based, you'll need to rinse your brush beneath a faucet.
How it works
What Is It?
The Tapley Brake Test Meter is a scientific instrument, indisputable in its accuracy as it is based on one of the basic laws of applied physics. It consists of a finely balanced pendulum free to respond to any changes in speed or angle, working through a quadrant gear train to rotate a needle round a dial. To damp out all vibration, the instrument is filled with a special fluid not sensitive to changes in temperature. No maintenance is necessary. The same meter can be used to test all types of vehicles, from heavy trucks and buses to vans and passenger cars. It needs no electrical connections and it's so portable that you can take the Tapley Meter to the vehicle instead of the other way around.
Test Procedure
To set the instrument for a brake test, start by loosening the two butterfly nuts at the sides of the swivel-mounting bracket. Tilt the head until the main needle (with arrow) is set at 3.5 if the unit is in meters or 13.4 if in feet with the face of the instrument JUST BACK FROM THE VERTICAL. This is important because it can be set with the face nearly horizontal, but it would then be near the end stop and would not move anticlockwise. When set in this manner the butterfly nuts can be tightened again, and the instrument is ready to start the test as pictured under the Gallery tab above (1st image).
With the main needle set, the recording needle (without arrow) should be turned clockwise by means of the chrome knob in the middle of the dial until it is against the left hand side of the main needle. The vehicle is then driven along a level road at about 20 miles per hour or 30 kph, and the brakes fully applied by means of the foot brake pedal only. When the vehicle has stopped the brake efficiency reading can be taken from the figure shown by the recording needle on the inner brake scale. Stopping distance readings are taken from the outer scale figures. A similar reading should now be taken from a lower speed using the handbrake only.
Advantages
- The Tapley meter is very robust and has low maintenance costs.
- Readily transportable weighing only 10kg complete with its protective casing.
- Simple to operate and needs very little operator training.
- The recommended recertification interval for a Tapley meter is every two years and this is carried out at low cost by us, the manufacturers.
- The Tapley meter has been a recognized international standard decelerometer for almost 100 years and is certified to a standard agreed by the National Physical Laboratory in the U.K.
- Results of Tapley meter tests are accepted as evidence of braking efficiency in Courts of Law throughout the world.
