Any change to the braking system requires cert. Including changing the brake pedal to a skinny one instead of fat auto pad.
Even if using factory parts. It is not the pedal setup the car left the factory with.
Wof audit man used our workshop as a neutral zone to go over a vehicle that someone had flagged, owner tried explaining he was using the loophole of using factory parts.
Audit guy asks if the brake pedal is the one that specific car left the factory with, owner says nah i swapped that too as the original was too wide. No loophole exists.
Even my XC, don't even have to change the pedal box, just slide out the shaft the pedals hang on, and slide the manual pedals on. Still a fail due to brake pedal itself being changed.
Not trying to go on or be a dick about it, just don't want anyone getting caught out.
A bit shit when all things are equal, but rules are rules.
