Anybody modify rear brake for stability control?
And does it pass AFM and Track day tech inspections?
The brake would technically work but very poorly and have lots of play in foot pedal....
As has been addressed in the previous replies, yes, modification of the rear brake is allowed.
Help us help you:
What is your intent with the proposed modifications? What are you experiencing now that you want to fix? What do you mean when you state “for stability control”?
I’ve previously done everything listed above with the exception of placing a ‘jet’ in the brake line. That one appears less than ideal because it not only restricts fluid flow in application of the brake, but also when releasing the brake. It is not something I would do.
If you look at many high level race bikes you’ll likely see the stiffer spring on the master cylinder. I’ve seen many with what are obviously an old or spare valve spring installed.
To ask again, what is your intent when it comes to using the rear brake? Do you have a problem you need to address, or is this just a theoretical thing right now? The above listed modifications will all have some sort of effect. I’m unclear on how this will address stability control. What is your goal?
