Is a brake servo really necessary - thinking SE5.

For MOT, technically yes. For stopping the car, no.

Thanks Jim. If one removed the servo completely, would that still fall foul of the MOT?

Officially, I believe so (brake servo missing or inoperative) unless the vehicle is modified for a specific purpose such as Motorsport - but they are looking for other supporting mods such as a roll cage, harness and seat changes to accompany it.

Jim has just answered a very similar question on another forum..
13 Extensively modified vehicles
If a vehicle has been extensively modified or converted, certain defects, such as for components ‘missing where fitted as standard’ shouldn't be applied, for example:
• a car converted for competition rally use must have the rear seats removed, be fitted with a roll cage and full harness seat belts, may not be fitted with components such as brake servo, power steering or airbags
• a car converted to a stretch limousine may no longer be fitted with items such as curtain airbags or a functional electronic stability control system

This exemption doesn’t apply to vehicles with minor modifications. Therefore, a car fitted with rally style seats, body kit and a sports steering wheel wouldn’t be exempt from the requirement to have a driver’s airbag if one was fitted as standard equipment.
Vehicles modified for disabled use must be assessed on their merits. For example, it's acceptable for the driver’s airbag to be removed for a wheelchair user, but the SRS warning lamp mustn't indicate a system malfunction.

Having said that, my car, a 5a, was bought with an MOT, but no servo. It has one now though and is the better for it.

Most MOT testers wouldn't know if a SE5 had a servo as standard or whether it was an optional extra, so you would be unlucky to fail an MOT if the brakes work effectively
