Some 2002-08 Mazda B-series pickups may come into your store because the rear brakes are grabbing or locking up.
Mazda says the condition usually occurs during the first few pedal applications following a prolonged soak and is most likely due to moisture intruding into the rear brake linings.
Replacing the brake shoes and sealing off the backside of the brake backing plates with silicone sealant at the axle flange, hold-down pins, wheel cylinders and parking brake cables should eliminate the concern.
