Our Hydropower hydraulic brake assist power booster fits 1963-66 Chevy and GMC truck and generates up to 1800psi of line pressure to the brake calipers. It is fitted our new POL master cylinder and a Black Out Series adjustable proportioning valve. After numerous requests we have made our all new aluminum master cylinder the choice for these kits. It outperforms Wilwood in all areas including safety or your money back. This kit is powered by hydraulic line pressure from the power steering pump. Firewall and valve cover clearance is equivalent to a 7" diameter vacuum booster. The firewall brackets are correct for 63-66 GM truck applications.
The average power steering pump puts out from 800psi to 1400psi line pressure. The Hydropower® uses this to convert to pressure to apply against the master cylinder. This greatly improves stopping performance and driver feedback. These hydraulic power boosters can be easily installed on an existing vacuum boosted vehicle or used to convert a manual brake setup to power with ordinary hand tools and average mechanical ability.

Love these
Size: 11.5 Wide, Color: White
For a plus size, tall woman that feet swell these sandals were perfect.They were not tight.They're very comfortable.The straps adjust perfectly and have a little bit of stretch in them.I was able to walk with them with no issue.They actually have great traction on the bottom.And surprisingly very durable.

Super comfortable and extremely flattering
Size: 9.5, Color: Black
Love! Love! Love! Even though they are very flat sandals, the soul has just enough cushion to feel like you’re walking on a cloud. I also love the location of the straps. As someone with bunions, they cover them perfectly and make my feet look attractive while not being completely covered.

Comfortable at first, but didn’t hold up long-term
Size: 8, Color: Tan
The size felt true and the feel was comfortable right out of the box. I liked the softness of the footbed, and the wearability was good for everyday errands and casual outings at first. Unfortunately, after about six months of regular use, they started falling apart. While the versatility was nice and the thickness felt fine for warm weather, the overall durability just wasn’t there. They’re okay for short-term use, but I wouldn’t expect them to last long.

Great quality
Size: 10, Color: Tan
Great quality leather sandals I bought to replace a worn out pair. They are comfortable and not stiff. Hoping the rubber sole lasts a long time. They look nice with jeans, shorts or casual dresses.

Beautiful, well priced, and no discomfort!
Size: 6.5, Color: Taupe, Size: 6.5, Color: Taupe
My daughter wore these for her HS graduation ceremony. So beautiful, well priced, and she never complained about any pain or discomfort. The only downside was that she got an X tanned on her feet! 😆 So put sunscreen on your feet before wearing these.
