QuestionI have a 1995 Chev K1500 V6 4.3L On Friday I took it in to have the brake pads replaced and lines flushed. It since has shown a problem, where my mechanic told me to take it to the dealership for a proper diagnostic to make sure correct problem would be fixed.
I recieved a phone call saying that my rotars are warped, and that the hub assembly on the left side is bent. The total cost to replace the 4 components will be $1300. My mechanic took off the rotars and filed them before putting on the new pads. I did drive my truck for about 5 miles and confirmed that there were further issues.
Could that small drive be the cause of the warping, or is the dealership trying to take advantage of me?
Also, am having problems with my wipers. They basically work when they want to, (and never in the rain) I was told that it was the Wiper module. I can not find a part called wiper module in any auto parts company or catalog, is there another name he means?
The person at the dealership is very abrupt with me and talks down to me like I don't know anything. I would like to be a little more knowledgable before I tell him what he can or can't fix. Or maybe take it to someone else completely.
Thanks for any thoughts.
AnswerBrake rotor tend to warp usually when the brakes are HOT and you drive thru a water puddle which splashes cold water on the rotor and causes them to warp. depending upon the amount of the warpage, the rotors can sometimes be MACHINED back to normal and if NOT, You replace them and you ALWAYS replace BOTH SIDES. NEVERreplace just ONE rotor.
The hub being bent is a little strange but a good technician can perform what is called a RUN-OUT test on the hub to verify it being bent.
As far as the wipers, In most cases the 3 bolts that hold the wiper motor to the fireawll are rusted thus not providing a GROUND path for the wiper motor.
remove each bolt, ONE AT A TIME and wire brush it clean and re-install it. Do this on all 3 bolts and see if this solves your problem. (This is a very common fault).
