First off, I wouldn't pay 400 for any kind of brake job.
If the cars brakes were still working, except for the grinding, your calipers are fine. they need to be replaced when they leak or start rubbing.
You can bypass the rotors if you want too depending on how long they were grinding. Anything more than a couple of days, they need to be resurfaced/replaced.
Sounds like a load of crap from merlins.
I don't even know how you could put the brakes on the wrong way.
The grinding noise is from safety clips on the back of the brake pad to let you know it is time to change them.
When the pad gets to low, the clips start rubbing against the metal rotor and you get the grinding noise.
These clips dig into the rotors and cut them up.
 
If only one brake pad was working, the car wouldn't stop!!!!! Brakes work by putting pressure against the rotors on both sides like a vise to slow the car down.
the harder you press the brake pedal, the higher the pressure is against the rotors.
And unless cows started jumping over the moon, Calipers are always locked in one position, it's the rotor that spins freely.
 
Your getting taken for a ride!!!!!!!!!!!!Run fast

Do you mean that you put it in drive but it won't move? If so, are you sure that it's the front brakes?

Could be contaminents in the brake line. This could restrict the fluid flow to from the master cylinder.
 
How dirty is the brake fluid in the reservior?
More details needed.......

Noise when braking or turning by linda333

Hi, has anyone run into a problem of a noise when braking, driving at low speed (30 miles or below) or turning. The noise sounds kind of like dogs barking. The rotors and brakes have been replaced recently (but the noise preceded the replacement). When I first replaced the parts, the noise went away for about a 1000 miles but has returned. We took the new brakes off and cleaned them (thinking it was dust). The noise went away but again came back after about a 1,000 miles. The car is a 2001 and only has about 36,000 miles on it. A few mechanics have looked at it but no one can figure out what the noise is.
Thanks!

Check the surface of the rotors. They could also be warped. Also check the wheel berings. You may also want to look at the calipers to make sure they are square on the rotor and the shoes are on correctly and seated all the way in.
 
You should also look at the mounting bolts and make sure they are not bent. They are cheap to replace.
 
Hope that helps

Thanks for your suggestions. I actually went online and found the TSB reports for my model...turns out that there is something with the tires...if I inflate them more than is prescribed the noise goes away...very strange! I'm actually going to get new tires so this issue should disappear.
