1986 Toyota Corolla Replacement of brakes

Depends on who does it.

Average pads are $30.

Rotors are $30 each, maybe $45.

Calipers are $30 each plus core.

So, $160 in parts, labor is 2 hours @ whatever the shop charge is.

Most shops will mark up parts (list vs cost) and labor rate is $65 to $150 per hour.

Shop around, especially at dealers , they are hungry for business due to economy.
