Thread: i have a 1993 mercury grand marquis ?

im having trouble with the driver side piston. i bought a new caliber yesterday. ad tried to install it but i discovered that only a small amount of brake fluid is flowing through the drivers side front compared to the passenger side. what may be the problem and how to repair this ?? thanks in advance

it might just have air in the line. i would just put it on and bleed the air out of it.

probably the brake hose on that side or possibly the porportioning vavle I would crack the line loose from the hose and see if you have good flow there if so replace the hose if not do the same at the proportioning valve.
