I have a 1997 Chevy Suburban and the brakes suddenly started feeling spongy (which is a different question) - I went through to inspect all my brakes and front brake pads look fine/reasonable wear, and the passenger side brake drum pad looks about the same wear as the front disc brakes.
However the drivers side rear drum brake the shoes are worn down probably 2x as much, I'd guess that they probably should be replaced at this point. But the drums feel fine - no visual grooves and they feel smooth when I run my fingernails in and out on the drums.
Is that kind of uneven wear between passenger/drivers side normal? Or does that indicate some other issue?
