It takes about 2.5 to 3 hours ( I've done it a few times ) As for 'how much it costs' -that depends who does it
The part cost $75-100 and for labor to have it replaced expect to pay $200 if you don't do it yourself.
DOT 3 brake fluid
dot 3
For a 1997 Mercury Sable : ( DOT 3 brake fluid meeting Ford specification ESA-M6C25-A )
'P'arking or emergency brake
What kind of brake problem(noise,pulling)?
The MAP sensor should be on the firewall just above the brake booster.
3/16
On a 1999 Mercury Sable : In the fuse panel by the brake pedal : ( # 17 is a 30 amp fuse for the front wiper / washer )
no, it should be in the cabin under the dash and above the e-brake with the rest of the fuses.
The brake master cylinder would be bolted to it.
If you mean the exclamation point and the " P " above the word " BRAKE " in the lower right side of the gauge cluster in a 1998 Mercury Sable that means either the parking brake / emergency brake is on , or the brake fluid level in the brake master cylinder in your engine compartment is LOW
