nope $450 is close to what it would cost to completely restore equivalent drum brakes: new drums/hardware/shoes/backing plates

You can rebuild rear drum brakes less than 1/2 that number.

Drums = $40 each
Spring Kit = $16 each
Adjuster = $ 8 each
Wheel Cyl = $15 each

Shoes = $35 set

That's a total of $193 at NAPA. You could take another $20-$30 off this if you buy there low line parts.
