Morning,
In the process of preparing a track day VTR. Went for MOT on Saturday and failed due to the service brake not working correctly and rear brakes recording little or no effort. Having done some research it seems these faults can be associated with the brake pressure regulator being faulty or incorrectly set up.
Having replaced the rear beam I replaced the regulator at the same time. I am now questioning if I have the incorrect part because it doesn't have the large spring that connects to the trailing arm. Do I need to drill a hole on the new part and fit the old spring?
How the old part looked
New part
Thanks in advance
