Hi, My brakes are squeeling real bad.
Ok, How long has been going on.
A few weeks.
When was the last time you had work done on your brakes?
I bought the car a year ago and I haven't done anything since I got it.
Ok, well an inspection will run $65
Ok and what do you charge if I just need brake pads?
$100 for the front and $75 for the back if you need pad and machined rotors.
What if the rotors are bad too?
Pads and rotors for the front are $200 and $150 for the back.
OK, well, I know I need some work done.
Yeah, you definately do not want to go much longer with bad brakes for a lot of reasons. 
What are some other issues that can cause?
Well the biggest is your break could fail entirely. Also, you can wear out your brake calipers which can be really expensive to fix.
Do you think I have done that? Its been two weeks since I notice the sound? I had to wait until I had a free check to get the work done.
I can understand that, but if they are just squealing and you are not hearing any grinding, you should be ok.
OK
Best way for me to tell is get under there and take a look.
How long does an inspection take?
Long as it takes for me to get your wheel off.
Ok
I will know right away what you need.
And before you begin any work can you let me know what I need done?
Certainly, I won't do anything to your car you do not want done.
Ok, well can you do the job today, Like take a look now?
Sure, I have one person ahead of you but we can look.
OK, do you think you can finish the work today, even if I need pads and rotors?
Oh yeah. It is early enough in the morning we can get you fixed up today in a few hours.
