MOTs in Cheltenham
Checks for tyres in Cheltenham MOT tests
Amongst other elements, tyres will be checked for the correct type and structure, paying attention to the aspect ratio and the nominal size, attempting to maintain a similar diameter so that the drive train is not affected.
The type of tyre structure will also be looked at to see whether tyres are radial-ply, cross ply or bias belted.
Steel or fabric can make up Radial-ply tyres.
The wall of the tyres should also outline the sizing information, and is usually accompanied by load index, ply rating and the speed symbol.
Tyre depth must be a minimum of 1.6mm continuing around the tyre and should cover the central three quarters of the rubber surface.
In addition, tyres should be free from any damage or bulges or show any exposed cords as otherwise there is a possibility that it will not pass the MOT test unless tyres in question have been replaced.

Fuelling and emissions testing in Cheltenham
Car fuel and exhaust systems should be checked for excessive fume emissions and to determine whether all mechanisms are running smoothly. When the exhaust system is due for an examination, components such as catalyst converts will be checked, to look for faulty parts or blockages or areas that have deteriorated from corrosion which can be caused by salts in grit on the roads in winter. Exhaust systems with any leaks present are highly possible to fail a MOT in Cheltenham.
In addition to this, the amount of exhaust fumes can result in MOT failure if levels of carbon dioxide, hydrogen and lambda are considered too high. Damaged lambda or oxygen sensors can be responsible for damage to catalytic converters and emissions failures due to unburnt fuel having to pass through the exhaust pipe.
Checking brakes on cars in Cheltenham
Brakes provide vehicle safety, which is why MOTs test MG brakes so strictly. Moving cars are slowed and stopped by road brakes or service brakes, whereas handbrakes and parking brakes on the rear wheels hold vehicles when parked or stationary in traffic.
Tests to assess brake performance are conducted to determine efficiency of brakes, completed by putting cars on roller brake machines and undertaking gradient tests. Brake parts are examined to check that there are not parts causing leaks or pipes and flexible hoses vibrating, rigid pipes are not affected by chafing, kinks or fouling from friction off other items and reservoirs for vacuum, hydraulic and air brakes are leak free and secure.
Should Volvo brake performance be reduced on your car, you don't need to wait for your MOT test before consulting with Cheltenham garages.
Assessments made of car lights, mirrors and horns in Cheltenham
In order to meet legal requirements, visibility has to be clear. Therefore windscreen wipers leaving marks across the windscreen, cracked or broken wing mirrors or faulty horns, can be responsible for MOT failures.
At least two mirrors should be present on all vehicles to ensure that clear visibility is maintained behind the vehicle. Lights must also be in full working order, with headlights requiring white or yellow bulbs, of which colours must be matching.
Switches for the purpose of operating indicators, headlights and rear lights must be able to react immediately. Main beam lights must also turn on and off accordingly, and switch to dipped beam lights to avoid blinding oncoming vehicles with dazzle.
