robfg67 Posted July 4, 2009 Posted July 4, 2009 I replaced my internal slave cylinder in the BA10 5-speed with an OEM and the pedal feel is unchanged-there is only about 2" of resistance. I followed the bleeding instructions in the Jeep Factory Manual. Do I need to use a vacuum pump to more forcefully purge the air? Would this technique be worthwile: Could it be a bad clutch cylinder? I have no brake fluid leaking onto the fuse box, but could the cylinder go bad without any leaking?
Eagle Posted July 4, 2009 Posted July 4, 2009 To verify -- you bench bled first, and installed the new slave with the plastic tie still holding it in the compressed position?
robfg67 Posted July 4, 2009 Author Posted July 4, 2009 I did not bench bleed the slave cylinder. I did NOT remove the plastic straps.
Eagle Posted July 5, 2009 Posted July 5, 2009 Aging memory may be faulty, but I thought the FSM called for bench bleeding it before installation. Let's see -- so you installed it with the retaining band intact. You bled it. Have you since stepped on the pedal with the bleeder closed and busted the retainer band loose? If so, you may have a tough time getting it bled. You'll get there ... eventually ... but it may take awhile.
robfg67 Posted July 5, 2009 Author Posted July 5, 2009 I'll have a brake bleeder vacuum pump this week. Hopefully, that will do it.
BlueXJ Posted July 5, 2009 Posted July 5, 2009 I'll have a brake bleeder vacuum pump this week. Hopefully, that will do it. Please report back on this because I have it to do next weekend. I have a Mity-Vac to use if needed.
robfg67 Posted July 5, 2009 Author Posted July 5, 2009 Will do! My next day off is Wednesday, so I'll have a report back then. Again, does anyone know if a clutch cylinder can fail without dropping its fluid onto the fuse box?
Wildman Posted July 6, 2009 Posted July 6, 2009 Will do! My next day off is Wednesday, so I'll have a report back then. Again, does anyone know if a clutch cylinder can fail without dropping its fluid onto the fuse box? Yea, a master cyl can blow out internally. But its more likely for the soft line to swell up and become obstructed. Hopefully you spent the $18 for a new fluid line and changed it out with your new slave cyl :yes:
robfg67 Posted July 6, 2009 Author Posted July 6, 2009 I'll try to force bleed it on Wednesday and if that fails, I'll buy the OEM clutch cylinder & hose.
robfg67 Posted July 8, 2009 Author Posted July 8, 2009 Of course the bleeding pump didn't work. This is such a pain in the a**! :wall:
