Hey guys,

I need some advise from the brake specialists out there.

My rear pads are due. The rotors look ok, but my local garage guy suggested I change both at the same time to get better performance. He advised against putting the rears on a lathe since they're not very thick to begin with.

My plan was to swap in some Hawk HPS pads and DBA 4000 rotors, but the rear DBA rotors won't be out for another few months.

If I change pads now and rotors later, will this have a negative impact on brake performance down the road (once the DBAs are installed)?

Thanks,
js.

My rear disc's are pretty grooved and all I did was put pads on and they're fine. Now if your gonna put new rotors on later, you'll need to change the pads too. My suggestion would be put some cheap pads on for now and get the Hawks when you get the new rotors.

it's preferable to change both at the same time , the pad and the disc must wear together to get 100% of the pad surface in contact with the disc

i got the Hawk HPS on my mazda3 i love them , way better than the EBC green stuff (they are noisy when cool and make a lot of brake dust)

any shop will recommend doin both for 2 reasons. one is to garranty no come back as just replacing the pads might cause a noise, either on the slight rust build up at the edges or they might squeak. reason two is more money. i got away with just pad replacement front and rear. if you're replacing them your self just do the pads.

I just did my rear brakes (pads only) at 15k miles, if your rear discs dont look real grooved, you should be fine with just pads untill you need them again.The hawk pads are great but can be a little noisey, I would suggest akebono or qualtran pads, they are both high quality and not very expensiveIam an ASE certified master tech with almost 20 years experience, jjust my 2 cents.

Just do the pads and run the disks until they are wore out- extremely grooved beyond being reworked easily or close to min thickness. You might feet a squeek, but you can adjust them and useually get rid of it. Also saves money. Reason for mechanics recommendation is most likely as stated above.
