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!

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...

Just installed them and braking is smooth

Just installed them and braking is smooth. Remind me in about 6 months and I'll let you know how they're doing then.

Hi Jeremy, we're glad to hear the braking feels smooth! We'll be here to check in about six months—thanks for choosing SSBC-USA!

Great kit for the 2nd gen Dodge Ram 1500

Great kit for the 2nd gen Dodge Ram 1500. Braking power is drastically improved over the OEM drums.
