    Questions About Brakes

    Hi All,

    I've got a 2013 WRX with the original OEM pads still on, and it just turned 50k miles.

    There's a bit of shudder going on after the brakes get heated up coming down a long mountain road, or a few laps into some HPDE driving. This is a new thing. When they cool back down everything is fine. No shudder and the car stops as good as ever.

    A few weeks ago the dealer did an inspection of the car during servicing, and they gave the brakes a green light all the way around. I've read a lot of other posts, and I am still not sure where my issue falls into line.

    My understanding is that if the rotors are warped, they're always going to give a shuddering in the steering wheel. But if the issue is material buildup on the rotor and the shudder goes away, it has nothing to do with the rotor. If a rotor needs to be turned, can it cause the brake material to build up and cause the temporary shudder?

    I eventually want to get the Hawk HPS pads, but don't want to jump the gun if a simple resurfacing fixes the issue.

    Thanks everyone, lots of great info on the site.

    Resurfacing will only put a band-aid on the issue.
    Best option is to look into some better rotors at the same time as new pads (Talk to the boys at KNS brakes)

    Also, do a little more research before jumping into HPS pads. They are well liked by some... but there are superior options for much cheaper.


    This is the best bang for the buck you will get.
    Heat treated rotors (much more resistant to warping)

    Also another excellent option, for a much cheaper price point

    I doubt the rotors are warped. I'd suspect the pads themselves instead. If the shudder comes from the steering wheel suspect the front pads. If the shudder comes from the pedal suspect the rear pads.

    I don't typically trust when they tell me my brakes are good or bad. You usually have to remove the wheel and calipers to get a good visual as to the real condition.

    I'll be honest I rarely go through rear brakes 50, 60k isn't absurd to me. But 50k on front brakes, that's way more than I've ever achieved.

    My record stands at 120K miles for fronts. I changed the rears at the same time for no apparent reason.
