TO change just the pads,you can usually find someone to do it for 90 dollars,cheapy ones from pepboys are about 30 dollars each,total should be less than 200 dollars total.
On average it can cost you about $150 - $250 axle. The variation in price can stem from the make and model of your car and the extent of any damage that may have occurred if the brakes went too long before being repaired. Total job costs for both front and rear brakes apprx. $450-500.
Call around to your local shop to get estimates. There is no way that I can give you a estimate without knowing the year, make, and model of the vehicle.
The cost to have brakes repaired can very greatly based on the quality of products, where you live, and who does the service. You can buy brake pads for cars relatively inexpensively. Brake pads can usually be bought for under twenty dollars. If you have a shop replace them it may cost hundreds of dollars to have done.
Depending on the make of your car, and if it has disc brakes, drum brakes or both, the average cost will vary, but expect at least $200. If your discs or drums need to be turned, or if you need to replace your master or slave cylinders then much more.
