Overall Assessment

Customers applaud the brake booster master cylinder bracket tree for its easy assembly and high-quality material. The product showcases excellent fitment which provides practicality and usability, a feature that sets it apart from competitors. The instructions received mixed feedback but the product quality outweighs this minor issue. It is evident that customers are highly satisfied with the product and highly recommend it, although it would be more appreciated if it came with a speedway sticker.

After installing a 540 in my C10, the stock booster would not clear the valve cover, we also had switched to Wilwood disc brakes front and rear. Assembly was clean, clearance was plenty, I like the clean look.
