<div style="font-size: 12pt; font-family: helvetica,arial,sans-serif; color: #333333;"> <span style="font-family: helvetica; font-size: 12pt;">I used Carbotech a few times for front pads. I had lots of problems with them. Quality control is/was terrible. The backing plate was ground down to the friction material at the sides of the pads and they were not square. So, there was far to much clearance in the caliper slot. This caused the piston to torque once the brakes were applied. This makes the pads wear at an extreme angle and the pistons were leaving a witness mark in the bore from the induced torquing and side load. The hot friction material was making contact with the caliper casting. I talked with Carbotech a few times about this and they were completely defensive and said they sell a lot of these pads and no one ever complained about this problem before. They were not willing to check quality control or make them correctly. I took many photos and some video of exactly what was happening and made a direct comparison to standard pads and Hawk pads. The standard pads were NOS from a quality manufacturer, which I can't recall at the moment. Standard backing plate have a pretty tight fit in the caliper. I think I found .010" clearance. I found that the Hawk pads have very consistent production quality. So I switched to Hawk. I did like the feel of the Carbotech pads, but they really caused problems. </span>

<p class="MsoNormal"><span style="color: #1f497d;">Send the cores, along with brake drum specs (inside diameter so they can arc it correctly) and your contact information (phone, email and address) to the Carbotech address below (not their Cleveland location). They will give you a call back regarding the compound to use/recommended, based on type of racing (or street), vehicle drum size etc.</span></p>
