The product stands out due to its excellent quality for an attractive price, surpassing competitors' offerings. Although it may not fit all models (e.g., 1985 Elcamino), it is typically a practical and efficient choice for many consumers. A point of note is the inability to accommodate an Ebrake on specific models.

It's a decent kit. I'm just not a fan of using the Cadillac calipers. The parking brake is incorporated with the caliper piston and it can be a little tricky setting the parking brake distance. It also does not release very well once the parking brake is engaged. Once the pads wear some I think it will be better.

Wanted Ebrake, but mechanism doesn't clear the frame of 1985 Elcamino, placing on bottom of axle not a good plan. Wish I'd known that earlier. I ended up without Ebrake. I would have bought it without the Ebrake.
