What does rear break job means ?

[kulkarnipb]

I took my car today to mazda dealer for regular maintainece (like oil change etc). I picked up car later and since i have maintenance package, I paid zero amount. Later today, when I saw a comment on the invoice, which says I declined $336 job for rear break, I called dealer to check what does this mean but no answer. I might have to check on monday again, but just wondering if anyone has any idea ?
Does this mean replacing rear break pads or replacing rear rotors ?
Can anyone help me to understand pleaee. Thanks in advance.
See the attached screenshot of comment from Invoice.

You need to ask your dealer. It's probably replacing the rear brake pads and resurfacing or replacing the rear rotors, but that's just a guess, which is all anyone can offer you. I can tell you that Mazda MSRP for rear pads is $107.08, while each rear rotor has a MSRP of $83.35. You can get equivalent quality parts (and resurfacing services) at almost any auto store and do it yourself to save money - but you need to have proper tools and some basic knowledge of disc brake repair to do the job right.

Thx. Will check with dealer and will do it by myself at home.

I spoke to dealer and $336/- estimated charge is for - "Changing rear break pads and resurfacing rotors".
Really ? Resurfacing rear rotors costs that much for CX-9 ? Also is it needed really yo resurface rotors ?

When replacing the Brake Pads you should always resurface the rotors. If not the Brake pads will start wearing down in odd directions and you will eventually have to re-do your brakes much sooner than you thought.. or worse have to actually purchase new rotors!

If you're DIY'ing it you're way off just replacing the rotor than having the old ones resurfaced. By the time you pay a machine shop 15-25 each to resurface them and waste a whole lot of time having to quit the brake job half way through to take the rotors to a shop to have them turned, wait for them (probably next day turnaround so expect 2 trips), then put it all back together you're way better off just buying new ones so you can set aside an hour or so to do the job start to finish. Centric Premium rear rotors are $47 each at Rockauto. $104 after shipping and 5% discount code, vs $40 to have them turned. I don't know about your situation but an extra $60 is completely worth it to me to be able to do the job in an hour vs over 2 days with multiple trips to the machine shop. Plus I'll have nice new rotors that I know aren't going to fall below min thickness spec before the new pads I'm installing wear out.

Resurfacing only makes sense when you're a big shop and you have an on car lathe. They just pull the caliper out of the way then wheel the lathe over to each rotor. In 20 minutes they can turn all 4 rotors on the car without even having to remove the rotor.

Very good point. I am considering to replace rotors than resurfacing. Thanks for your valuable opinion.

IDK about you but good rotors cost about 80 bucks a pop for the CX-9. IDK what shop you got to that takes all day to complete a rotor job but my joint takes an hour tops. 10 Bucks a pop for the resurfacing... If your simply doing the back $20 bucks instead of $160... Yeah definitely worth it... Also you can resurface rotors 3-4 times before having to purchase new ones... If you like to blow cash.. Go for it and buy new ones

Centric rotors are really good rotors, and it's $104 shipped to your door just as I posted for a pair of rear rotors the the OP would need to do this job. I haven't found a shop that will turn rotors for less than $20 each in WNY since the 90's.

And lol @ turning them 3-4 times before needing new. Maybe if you ignore the minimum thickness spec entirely. I suppose you could take a brand new rotor and machine off the amount the lathe removes 3-4 times but you sure couldn't do it with a rotor that was actually being driven 10-20k between turnings.

Total delivered for the rotors and a set of centric premium ceramic pads is $121. That's all brand new parts and left than half the dealer quote and the dealer was just resurfacing the rotors. Assuming the OP could find someone with $10 rotor turning and the 1 hour turnaround time like your guy provides you could do the job for about $40. $80 is a decent savings but half the $160 you claimed. Of course with the turned rotors you run a much better chance of having them start pulsing a couple months after you do the job.

resurfacing rotors is old school. no need to do that unless there is a specific reason like brake deposits on the rotor.

throw new pads on, bed them in if you feel the need.

My 2011 GT needed a rear brake job at around 90,000 miles. I thought it was weird too but did it. They resurfaced the rotors and replaced the pads. I didn't notice a difference in performance, but did notice that the rear rotors were scored in a few places before the mechanic pointed it out to me.
