after changing pads,pedal is spongy

[blewbyu]

Thank you for your help,
I changed my lifetime PFCM pads, turned the rotors, and now the pedal is spongy, I guess that while pushing the pisotn back in, I either got air in the line, or ****** of the Master cyl. Anyone ever had this problem? Thanx

try bleeding the brakes .. u need to do the rear left first than the front left than the front right than the rear left.

Your right ... u may have gotten air in the piston

That is not the correct order to bleed the brakes. First start with the passenger rear, then the driver's rear, followed by the right passenger front, and finally the driver's front. In other words, always go with the furtherst brake and work your way to the master cylinder.

DougLee25, your method is old-school and doesn't apply to newer ABS systems.

Our ABS-equipped braked lines are divided LF/RR and RF/LR, a diagonal split.

Hence, you want to do the RR, LF, LR, RF. This agrees with the shop manual, BTW.

Another trick to help remove air is to go out on a gravel road and stomp on the brakes a few times to get the ABS to cycle. This supposedly works some air out of the systemmmm.

Thanx, more info is welcome, but thanx, I was not sure if it was like most of my other rides, or different with the abs, Thanx for the help

Sorry about that one. I for some reason thought his SHO was an '89. My bad.

Unless there is a breech in the caliper piston seal, there should be no way for air to enter the system unless you openend the bleeder screw. Did the pads seat correctly within the calipers? The SHO-specific PF pads for the 93 are the 4214S. The 4214 pads are for the smaller diameter pistons of the standard Taurus brakes.

exactly. I had Midas change my pads in my 2001 Taurus. It felt VERY spongy for a day or 2. I even brought the car back to them the next day (I was thinking it was air in the lines) The tech told me that was impossible because he didn't touch the bleeder valve). So digustedly, I drove off. The spongy pedal went away on its own. shrug

Hey Scott, does PFCM have pads for the rears of a 6/92-earlier? Just wondering
