Overall Assessment

Customers have reportedly been unsatisfied with the product's usability, stating that the brake kit doesn't work as advertised and does not fit a '66 Mustang, despite being marketed as suitable. Users experienced issues with the brakes locking up and brake equalizer and bracket collision. They also raised concerns about safety due to the lack of fitting instructions and union thread information. No positive aspects of the product were identified, suggesting significant room for improvement in terms of design and product information.

I installed this KIT and ftom the beginning the braket and proportioning valve do not clear a factory 66 mustang. Made new lines. Rears would lock up and fronts hardly work. Installed aftermarket proportion valve, still the same. I replaced ever hydraulic component at this point and the fronts barely work with rear locking up. This kit does not work as advertised.

The item is sold as a fit for a '64 to '66 Mustang however the brake equaliser and bracket collide with the suspension turret. requires new short bracket or the equaliser fitting to the inner fender, brake pipes to master cylinder will then be wrong shape/length. Incorrect ends fitted to brake pipes. No fitting insructions/union thread information supplied yet part is safety critical.

I noticed that the portioning valve has a electrical plug on it. Do you run power to it? If so is that a constant supply? I ordered the kit and it has ZERO instructions!

Would this kit work to replace the power booster on an original 1966 Mustang Power Drum Brake car? I'm looking to replace the original booster while upgrading to a dual master cylinder, but I'm not going with disc brakes.

You say use the rear and MBM say use the two front ones for the front disks and the rear for the rear . there's makes more sense .(Off the proportioning valve) Please find the right one .Thanks again .
