Hello,
2015 Mazda 3 s Touring here
ive had an issue since I did my first brake job. The issue I am having is an intermittent brake judder in the steering wheel under light braking. Goes away at harder braking. Also sometimes it doesn’t happen at all while breaking
i ended up buying new rotors and pads (advance auto/ autozone respectively) and did the whole brake job over again. All was good for about 3000 miles until the same problem happened again.
Figured it was a thickness variation on rotor (maybe because ceramic pads) so someone suggested to try re-bedding the brakes in again. That worked good for 200 miles, but it comes back. However another re-bed attempt gave it another 200 miles of good breaking
I believe it is a pad deposition issue because after driving in stop/go traffic that’s when the judder comes back.
not sure what to do, any suggestions?
thanks
I would double check and make sure all the slides are clean and lubricated moving freely as well as the pads in the hardware so they’re not sticking or dragging and also verify the torque on the wheels. Over torquing the wheels can cause rotor distorted in some cases
It’s not the wheel torqued, got it with the torque wrench to 90ft/lbs. slides are definitely lubricated and I can spin the wheels while the car is jacked up. Would there be a good way to fix pad deposits on rotor without resurfacing/replacing them
You can try going over them with sand paper or a scotch pad. Scuffing and crosshatching is good for the rotors and prevents brake noise
Also resurfacing will only shorten the life. Every time the rotors are resurfaced they only get thinner and become easier and easier to warp
