Seems like the prices are high here. After reading threads a while back about $2000 front only pads and rotors jobs, I was scared. Then the sensor came on at 28k. Cost: Dealer pads and sensors (is the sensor really necessary - I guess you can't turn in a leased car with a sensor error) are 170+50 = 230 (sic) +tax and my reliable mechanic said he'd install the for 70. 300+tax is a pretty good deal. Thanks god the rotors are fine.
I assume we have not spoken, because if we had you would realize that you paid a lot of money for the parts you bought!
In the kit outlined here, the pads and front sensors cost $94 total, no tax except in MA., and the balance is for other necessary components. So you paid an extra $126, which would have paid for 1.3 brake rotors approximately in the kit described. In fact, the kit today is $306 plus the freight charges! This will increase due to the Euro/dollar exchange and other factors on Feb 1., but that will be the first actual increase in prices in 30 months! We have consistently added components to make the brake work complete and precise repair work for the DIYer or professional mechanic. That is the only reason the price has grown over this time.
The $2000 brake work was for a four wheel brake job, BTW. That is what the dealer would charge in many parts of the country. Clients for this brake kit have been able to do their complete four wheel brake work for half
that amount with hired labor or less
if done by themselves.
Yes, the sensor is necessary, especially if yours went off, as this indicates the sensors are damaged and no longer carrying an electrical current. The comment you made about your leased vehicle - well, if you are returning a leased vehicle shortly, sure, I can see why you wouldn't want to spend money on it for repairs, except the minimum. But if you are keeping the vehicle, then the full treatment is the only approach.
I also want to mention, that depending on the lease return inspection, it is conceivable that your not replacing the rotors would come back to haunt you, if the party receiving the vehicle back makes sense of what work you have done. Frankly, if the pads were worn down, so were the rotors, ipso facto, you haven't repaired correctly - that is the soft, white underbelly for your situation. The rotors are a soft material and the pads grind them down progressively as they wear. It's like A=B, B=C, then A=C in mathematics.
Please be aware that saying this brake package is expensive is simply not a fully considered answer in light of all the facts. I am available for discussion at my number below.
