95 GMC has a closed system (no bleed). My truck is at 286k miles with the original system parts still in place. The hydraulic line recently blew out so I ordered a a complete new system from Rock Auto but am having difficulty snaking the old one out. I'm trying to keep it intact so I can reverse the process with the new parts. Any hints as to ease it loose? Should I be feeding/pulling from the top or the bottom?

 

It’s unlikely to make much difference, but please provide engine size, chassis (1500/2500/3500) and w/ or w/o 4x4.

The exact removal process can also vary depending on what emissions systems are on it (ex. w/ or w/o smog pump system).

Also which kit did you purchase?

 

Hello Gumby22, 95 GMC 1500 2wd 5.7 motor, 5 spd .no smog pump with Gibson headers that y connect just to the rear of the slave cyl. I had no problem getting the slave cyl unbolted and pulled out. My new unit assy is a SACHS p/n S2 SPH044. Thanks for your help.

 

Sorry for the delay - It was difficult to find anything more than very basic service info for your truck. All I could find was a generic procedure that basically states to unbolt the components and remove them from the top end of the engine bay.

I have no direct experience with the pre-bled kits, but I’m pretty familiar with the trucks of this era, so here’s what I can offer for advice off the top of my head:

1) It may be necessary to separate the steering column from the gear and/or drop the exhaust pipe depending on clearances.

2) It will probably be beneficial to remove the driver side tire for accessibility.

3) If the clutch feels like it needs to be bled after installation, it’s easier to remove the slave cylinder, hold it with the line end up, and slowly push the rod in. Make sure the reservoir cap is removed and any air will be pushed out of the top of the reservoir.

4) Sachs may have more detailed instructions included with the kit and/or on their website.
