Required to remove Torx (E8) male thread screws from 1990 Buick Lesabre drum brake cylinders. DO NOT put a 1/4" socket in a tight space, so this wrench is/was critical. And, wow, it worked great. Don't you love it when the plan works? What a relief.
The product arrived in a plastic bag, with no anti-rust materials or preventive measures. The instrument was very rusty on the outside. The photo shows the tool in a tightly sealed package. Very deceptive. I would send it back if I didn't need it.
This was perfect for replacing wheel cylinders on my 2000 Chevy Malibu. I had to use the end of the E-10 key. It fit perfectly, was angled just right for turning and long enough to get good leverage in tight spaces. I didn't have to remove the wheel hub and skid plate to remove the wheel cylinders, which saved me a lot of time and effort. It also saved me money since I didn't have to take it to the mechanic. Even if I only use it once, it's worth the investment.
