MOTs in Dorchester
MOT tests in Dorchester covering wheels and tyres
Amongst other elements, tyres will be checked for the correct type and structure, including aspect ratio and nominal size, so that ride height is not dramatically affected. The tyre type will also be noted to determine whether they are bias belted, cross ply or radial ply.
Tyres that are radial-ply can be fabric or steel construction. The tyre wall also has to display the tyre size information, and generally is accompanied with a load index, ply rating and the speed symbol.
Tyres will be checked with a gauge to ensure a tread depth of 1.6mm continuously around the tyre and encompassing the central three quarters of the surface of the tyre. In addition, tyres cannot have any tears or bulges or display any cords otherwise the vehicle will fail the MOT unless sufficient tyre replacements take place.

Dorchester fuelling and emissions testing
Fuel and exhaust systems should be assessed for any increase in noise and to evaluate whether all mechanisms are running properly.
Upon close inspection of the exhaust system, components such as catalyst converts will be checked, to look for any parts which may have developed holes or parts that could have deteriorated which can be caused by salts in grit on the roads in winter.
Exhausts with major leaks are unlikely to meet MOT criteria in Dorchester.
As well as these elements, the exhaust fumes can also result in a failed MOT test if levels of carbon dioxide, carbon monoxide and lambda are too high.
Ineffective oxygen or lambda sensors can be responsible for damaged catalytic converts causing more emissions due to fuel having not been burnt and passing through the exhaust pipe.
Assessments made of car lights, mirrors and horns in Dorchester
In order to ensure vehicle safety, visibility should be kept at a high level. Therefore fault wiper blades, broken or missing wing mirrors or horns that are inaudible, can be responsible for MOT failures.
Two mirrors should be present on all vehicles to enable clear visibility of vehicles behind the car. In addition, lights should be clear and working, with headlights comprising of white or yellow bulbs, and colours must match.
Switches that operate indicators, rear lights and headlights must be present and not have delayed operation. Main beam lights must also turn on and off promptly, switching to dipped beam headlights to prevent oncoming vehicles being dazzled.
Dorchester garages can repair any problems with your car.
Dorchester checks made on brakes
In terms of vehicle safety, brakes are one of the most important components so MOTs test Lotus and Subaru brakes stringently. Road brakes or foot brakes are used to stop the vehicle when in motion, whereas a parking brake is used to secure the vehicle when parked or stationary in traffic.
Tests to assess brake performance are conducted to see how effective brakes are, and are carried out through gradient tests and using roller brake testers. Brake parts are examined to check that there are not parts causing leaks or pipes and flexible hoses vibrating, chafing or fouling in rigid pipes, and vacuum or air reservoirs are securely attached and free from damage that could cause leaks.
If your MG car brake performance is compromised, you needn't wait for your MOT due date before consulting with Dorchester garages.
