phoenix1151 Posted March 13, 2016 Report Share Posted March 13, 2016 Yesterday, I replaced the front rotors and brake pads on my wife's 2012 SXT, and reviewed some general on-line info beforehand. One source claimed that depressing the brake piston to fit the new pads wasn't a good idea unless you bled some brake fluid out of the bleed nipple. They claimed that not bleeding fluid could cause damage on ABS systems. I bled a bit just in case, but wonder what others have to say about this, particularly on the Journey (and Dodge Nitro). Also, I only have some GM brand brake fluid in the garage (Delco Supreme II DOT 3 conforms to GM-4653M CMVSS 116, SAE J1703) but don't see any issue with using it to top up the Journey's reservoir. However, before I do, I'll ask whether anyone knows if there is any issue with this. Quote Link to comment Share on other sites More sharing options...
jkeaton Posted March 13, 2016 Report Share Posted March 13, 2016 Don't need to bleed anything when pressing in the piston. Remove the brake fluid reservoir cap to let the pressure off. May need to suction some fluid off the top if it's really full before you start. I use regular brake fluid. Dot 3 or 4 to top off. 2late4u and rolly 2 Quote Link to comment Share on other sites More sharing options...
2late4u Posted March 13, 2016 Report Share Posted March 13, 2016 i wouldn't use the old fluid first since it seams to be for GM specs, BUT also i never use old or opened that has been opened for a long time. first its not that expensive and i've always been told that a opened bottle tends to collect moisture .Not for sure that's true but its what i've heard...agree with what jkeaton said on removing the cap and then compressing the piston i've never had any problems this way... rolly 1 Quote Link to comment Share on other sites More sharing options...
BrianS Posted March 13, 2016 Report Share Posted March 13, 2016 Just curious, after you " bled a bit just in case" when you pushed the caliper piston back in, did you bleed the system after you installed the new pads and the calipers? If you opened the sealed hydraulic system, you should make sure you have purged all the air from it. FWIW, I've never opened a bleed screw to push the pistons back in... use one of the old pads and a large c-clamp. Put the old pad in place and tighten the clamp down until the piston is back in. jkeaton 1 Quote Link to comment Share on other sites More sharing options...
bramfrank Posted March 14, 2016 Report Share Posted March 14, 2016 Be aware that the rear calipers must be screwed back in using a rewind tool.And I can't imagine how pushing back the pitons would impact the ABS since it is essentially out of circuit when not activated.
