### ⭐⭐⭐⭐⭐ Wilton quality. Works well for my purpose
*by J***. on October 26, 2025*

Wilton quality. Works well for compressing truck brake calipers. So far I’ve tried it on ford and Ram 2500s and fits well. I’ve been able to compress the caliper pistons without much effort so it’s worked well for my intended purpose.
