So far so good. 2020 Cadillac Escalade ESV 6.2L 4WD. I'm still putting the first 100 miles on the new front brakes. Incredibly responsive coupled with stainless steel braided brakelines. Overall install took less than 1 hour with cleaning and torquing all fasteners and flushing and bleeding the front brakes. I will buy the rear brakes next.

Hi Jerome, thank you for sharing your experience! We're glad to hear the brakes are working well and that the installation went smoothly. We appreciate your trust and look forward to serving you again for the rear brakes. Safe driving!

Fit OEM bracket with no adjustment

Fit OEM bracket with no adjustment. Definitely stronger and smoother than the two piston original. Large fluid void in the caliper needs extra time and fluid to bleed but has top and bottom bleed options. I like the look of the new caliper through the wheel

Hi Nathan, thank you for sharing your experience! We're glad you found the caliper smooth and easy to fit, and that you like the look. Enjoy your upgraded braking system!

UPDATED

Everything worked out after modifying the ebrake cable. It's worked out fantastic and wish I had done the conversion sooner!

I'm hoping to edit this review soon. Delivery was pretty good only a day later than expected. Everything seemed to fit fine although the brake lines needed to be modified. The only standing issue right now is the ebrake cable is apparently too short, so it's not ready for the road yet. I'm considering options before road test. Again, I hope to edit this soon and make it a five star across the board.

Hi Gary, thank you for your detailed feedback! We're glad the delivery was timely and that most parts fit well. We appreciate your efforts to resolve the ebrake cable issue and look forward to hearing about your road test. Feel free to update your review when you're ready. Safe driving!

Did a complete manual brake to power assisted disc brakes

Did a complete manual brake to power assisted disc brakes. Was very difficult finding the correct otems to fit a 1971 Duster but Chris and others were great to work with and we finally got everything correct. I appreciate their patience as we worked through rebuilding an old car. The entier team (tech and Chris) were great.

Thanks...

Hi Glenn, thank you so much for your kind words! We're thrilled to hear everything worked out well with your Duster project. It was a pleasure assisting you, and we're here whenever you need us. Happy driving!
