1.0 out of 5 stars Measure parking brake drum

B. · May 13, 2025

Rear rotors do not fit….parking brake drum is too small diameter. My rear rotors are 300mm same as replacement and Bolo fitment said they would fit…… they don’t. This measurement should be in listing. Also missing spring clips for front. Front rotors and pads fit as does rear pads.Missed return window, so I now own them.

1.0 out of 5 stars Rear rotors don’t fit, missing parts.

Started with the front brakes and found the kit was missing two pairs of guide pin bushings and plugs and two anti rattle clips. Emails to Callahan were met with “that’s all you get…everything was there.” Follow up emails were met with the same response. Then, after finishing the front install, the hat on the rear rotors don’t fit. Callahan wouldn’t do anything when asked if they would make it right and said get a refund. After I’ve already installed parts on the front?! Yeah, no. So, mid year 2014 BMW changed from 174mm to 191mm rear rotor hats. Check the build date on your car before you buy but Callahan’s customer service is a joke. I’m stuck with buying a second set of rotors and front anti rattle clips because Callahan WILL NOT make it right.

Great quality brake system - rotors are heavy duty, and brake pads are nicely upgraded. Provided everything needed for installation, from a parts perspective.

5.0 out of 5 stars Worth the money.

Fits on my 2015 BMW 228i Xdrive, it has everything, pads rotors and sensor, easy to install. Saved a couple of hundreds from the BMW dealership

1.0 out of 5 stars Compatibility

A.S. · April 27, 2024

it was advertised that this would fit my 2015 BMW 328i, with 312mm front and 300mm rear single piston rotors. However, only the front brake rotors fit. not to mention the kit only came with one brake wear sensor. The new rotors would not fit around the rear parking brake actuator.don’t buy these.

5.0 out of 5 stars i would buy again for my bmw

1.0 out of 5 stars Shudder and vibration after install

T. · September 10, 2019

Terrible vibration and noise from brakes after the install. I rebed them hoping that would help, it did not. Took a look in case some pad deposits have collected on the rotor and there was nothing. Almost like the rotors are warped or imbalanced.
