Diesels are an above average means of propulsion. There, I tempered it for you.

What is the opinion of Centric?

[curtis73]

I've used their products many times. They are a box brand - meaning they purchase products from other rebuilders and suppliers and stuff them in a box labeled "centric", but I've not noticed any specific weak points or problems with their stuff.

First time pad replacement I usually run my finger nail down the disk if no deep groves are detected or seen.
I just replace the pads with no bad effects.

My daughter drives fast & breaks hard & hers had a 1/2 nickle (5 cent) size hole in the edge of the disk so they needed replacement, no question about it.

glad you caught that that could've been a wreck there.

We had a few rotors at school from the Mercedes dealership down the road. Some lady came in and said her brakes were grinding. The whole side of the rotor was gone. She was braking on the vents in the center of the disk.

Generally, if its my car, I'll let a few light grooves go. If its someone elses, I'll tell them to buy rotors before I touch the car. Better to charge them a few bucks than to be responsible when they wreck.

you got that right i've done brakes and alignment for years well started doing that in 83. but yes there lives in your hands on those to parts. what if car dies or shuts down no big deal. i doubt they'll get killed but what were taliking about can kill them. glad you think the same..
