Travis Gene Hale –
Handle came off on like the 3rd brake job I did. The metal holds up fine, I ended up makeshifting a handle. Could not recommend for quality though.
Bishop –
I opened the box and it’s all scratched up. The condition of the handle is fine, but it looks like the handle could slip off any day now. I would have expected something like this if it were half off, but not worth the full price…
