The labor cost to replace brake pads and rotors on a vehicle is around $150.00 to $200.00 per axle.
Then there's the cost of the actual brake pads and brake rotors as well.
So you might end up paying a shop $300.00 to $500.00 per axle for the cost of the brake pads and rotors and the labor costs.
For me I had a shop replace the front brake pads and front brake rotors for $300.00
A smaller local shop could usually do the job of replacing the brake pads and rotors cheaper than say a dealership.
The dealership wanted $1,000.00 for parts and labor but I found the local shop to do the job for $300.00
There may also be mobile mechanics that would come to your house and do the job cheaper than an auto shop or dealership as well.
