Front Brake Rotor 2006 4X4
Well, The saga of the front brake job continues, this some good reading here....... So this is where I am, another day working on a Chevrolet Colorado front brake system, this makes day 3, I can't think of a better way to spend a 3 day weekend then taking a routine 2 hour job and stretching it into over 30 hours. The dealer would be lost at this point. They couldn't understand or try to figure out what was wrong. So I did some figuring with my pal Mike, short for Micrometer.
This is a 2006 4 X 4 LS, 4 door. This attempt to replace worn front rotors using genuine AC Delco Chevrolet parts. Just thinking I went to the dealer to pay top dollar and get the opportunity to use such a wonderful facility. I feel fortunate that I can use them, they made sure that I felt lucky they were there to help me. Yes, I'm the lucky customer. I'll always feel like i should kiss the feet of all that work for Chevrolet. They are the best of the best.
I started with wire brushing and cleaning all surfaces, then I installed the new from the Chevrolet Dealer rotor on the hub, then the hub on the front drivers side spindle. I torqued down all the bolts to where they are supposed to be. Before I installed the caliper I took a simple instrument and measured the space that the caliper was to fit into (space between the rotor and the surface of the caliper mounting face on the spindle), 0.210" showing on the mike. Now I measure the thickness of the caliper mounting bracket, same number 0.210" thick. OK this is what the problem is, fitting something into something that is the same size, it won't go! You need some clearance.
I'm at my wits end, so I called a very good/old friend of mine that owns a machine shop. I asked him if he could help me with this situation, "can you take off .0.050" from the inside surface of the rotor? "No problem", he said "bring um in tomorrow". Well I have known Eric for 22 years now, and I know him as one of the nicest people I have ever met. BTW he is a Tool and Die maker by trade, not a machinist. I'm very fortunate that I have somebody that will do this. I'm pretty sure this is the end of my post on this.
I have photos, but they don't reveal anything that isn't said here.
