Not great
- Initial install the bolt that travels inside of the master cylinder from the booster is way too small leading to nothing happening on first attempt to bleed (a longer bolt will fix this), also does not come with the fittings to be flared onto the brake lines as the factory ones will not screw on. Surface of master also completely rusted within 1 month of ownership underneath the bonnet. Will also be a pain trying to engineer this with the "big brake upgrade kit".
