Is this normal ? Sounds like indicators, not to loud , little louder when braking. Live on Maui so lots of hills, could it be pads this fast ? Does warranty cover this,? Anybody else have similar prob? Much mahalos
It could just be time. 20,000 miles of driving lots of hills and riding brakes for miles and miles will wear them faster than "normal" driving. Some people get over 100k out of their OEM pads some get 30k (usually because of lots of towing) you might get 20.
Like whippersnapper02 said take the tire off and check them or have a local tire/brake shop check them. Most will do it for free hoping to get your business.
Like Bojangles said Warranty isn't going to cover wear items.
Unless it's a manufacture defect you'll be paying for it.
