Vehicle: 2000 Chevy Blazer 4WD 4.3L V6 Engine
Current Symptoms (I suspect this might be the symptoms of 2 over-lapping problems?)
- Brake light comes on. It then goes off if I press the brake to the floor. (Comes back on after restarting the vehicle).
- Brakes are inconsistent. Sometimes I have to press them to the floor to stop, other times they only need pressed a little. This occasionally changes while driving, causing a bit of worry.
- Very loud squeaking when turning right. This is the newest symptom and it started today.
- I replaced the (front) Brake-pads less than 2 months ago, and I have a very good feeling they are worn again. Lots of dust on the (front) rims.
- Engine-light came on with error code: 0174 - System Too Lean (Bank 2)
- Occasional Hesitation on take-off. It almost seems like I'm holding the brake a little bit (I'm not) at first, then I give it more gas and it takes off (So it appears to other drivers that I wasn't paying attention that the light turned green lol).
- 1 Year Ago - Brake-pads and master-cylinder replaced as part of troubleshooting brakes going to the floor. (Turned out to be a sneaky leak in the back).
- 5 Months Ago - I got T-Boned on the Driver-side (from the middle of the back-door to behind the back-wheel). Broke the leaf-spring, blew the tires, and damaged the brake lines. Replaced all three (and a few other things).
- ~2 Months Ago - (front only) Brake-pads were grinding. Never heard any squeaking from brakes. Replaced (front) Brake-pads and flipped the rotors. Also noticed that the "casing" on the CV-Joint was off.
The reason I think it might be two different problems is that at first I thought the brakes were sticking (causing the occasional hesitation of take-off and theoretically causing additional brake-pad-ware) but after looking into the engine-error-code I'm thinking that is to blame for the hesitation. After all the engine would get louder if you hold the brakes and the gas at the same time wouldn't it?
What would cause the brake-pads to wear down so fast? (And potentially not squeak, because I suspect that the squeaking I hear when turning right has to do with the CV-Joint and not the brakes, it's like nails on a chalkboard x10).
I trust my Dad's decision to flip the rotors instead of replacing them, (I'll definitely look at them again when I get the chance though) so I'm going to guess for now that it's not them. The pads are obviously a symptom and not a cause (because I avoid braking heavy). When we changed the pads and flipped the rotors, the calipers looked a bit rusty (so I'm hoping it's them since I know how to change those).
Are there any other possibilities? I'm still fairly new to the inner-workings of a vehicle (more of a computer guy willing to learn as he goes), so just knowing what -could- cause something like this is helpful so I can at least research it further.
