Hope this helps,
3. Check that every motorcycle tricycle or motorcycle quadricycle is equipped with either;
a) two independent service braking devices fitted, one acting on the front axle/one acting on the rear axle which together operate the brakes on all the wheels
or
b) a single line service braking device that operates the brakes on all wheels
and
c) a secondary (emergency) braking device ( that may be the parking brake)
or
d) a dual/tandem service braking device which operates the brakes on all wheels
and in addition to any of the above
e) a parking brake device that operates on the wheels of at least one axle
Acceptable combinations are: a) & e) or b),c) & e) or d) & e)

you only need to brake one wheel for the mot. if you have a twin brake system
BUT for the vosa test all wheels on the same axle must brake.
if you have linked brakes, you must be able to reach the handbrake whilst seated on the trike and the all brake rule on the axle applies (emergency brake)

My opinion FWIW is regardless of what the differing MSVA/MOT/Construction & Use regs say, its common sense to have a decent handbrake thats within easy reach and works on both back wheels - you never know when you might need it! Its not usually that much more effort than making it work on just one back wheel either.

It does state one axle. There is a single wheel on the front axle. I've got a mate who built a trike and used a car rear calliper on the front disc and had the front wheel as the handbrake and that passed MOT fine as far as I know (he's taxed it twice since he did that handbrake set up so I'd guess it's been MOT'd like that)
With the extra wheel comes extra madness!!

Re: hand brake law
ALL handbrakes MUST be mechanical - trike, car, etc. You can't have a lever to push / pull a rod or cable to operate a hydraulic cylinder - it all must be mechanical. Download a copy of the Class 3 MSVA document - all info will be in there, as I assume you will also need a test unless this is a bolt-on conversion?3guitararmy wrote: ↑Tue Jun 15, 2021 11:32 am Does anyone know if a trike handbrake can be hydraulic or must it be mechanical ie cable operated as l have bought a nice trike but it has no handbrake fitted,any help appreciated guys.thanks

Re: hand brake law
Is there really a class c?
There is though I think a difference between the MSVA test and the class 3 test for a motorcycle conversion.
For the latter it only requires the handbrake to operate on one wheel or the tester where my partner goes is doing it wrong!
I was sceptical as to whether on a slope the trike would move but it doesn't with just the one wheel braked.
I wonder if being pedantic "a parking brake device that operates on the wheels of at least one axle" is with IRS rear the trike has in effect 3 axles or 1 axle at the front and 2 stub axles, drive shafts at the back?

Re: hand brake law
Not sure where the 'class C' came from but this is a very old thread! Only numbers now - 1 through 7 I believe.
Cut & Paste from the MSVA manual . . . . .
So you can't get legally on the road without the MSVA requirement but thereafter at MOT time only one wheel working is required - Daft!
And IMHO a IRS is classed as a single axle - the hubs are not independent having a single drive input so classed as linked and therefore a single unit.
Cut & Paste from the MSVA manual . . . . .
BUT interestingly the MOT testers handbook requirements for class 3 - ONLY requires 1 wheel to be locked by the 'parking brake'4. Check that every other tricycle or quadricycle is equipped with;
a) a foot controlled service brake device, that operates on all wheels
b) a secondary (emergency) brake device (that may be the parking
brake), and
c) a parking brake device, that operates on the wheels of at least one
axle
5. Check that the service brake system or systems are capable of being
operated from the riding or driving position whilst keeping both hands on the
steering control.
6. Check (where applicable) that the secondary braking system;
a) operates progressively
b) is able to be applied from the driving position while keeping one hand
on the steering control
7. Check (where applicable) that the parking brake system;
a) is able to be applied from the driving position
b) uses a control that is operated independently from any service brake
and can be positively locked on
c) is able to be held in the “on” position by purely mechanical means
So you can't get legally on the road without the MSVA requirement but thereafter at MOT time only one wheel working is required - Daft!
