One problem related to brake disc pads has been reported for the 1998 Acura RL. The most recently reported issues are listed below.
Rear brake pads were required to be replaced at 16552 miles due to wear. Front brake pads required to be replaced at 26,219 miles due to wear. Dealer claims that these are just "softer pads" and it is normal for the brakes to wear out this quickly. I don't buy it. No one has been hurt-yet.
