For the clutch?

LGAFF · 02-24-2010

Either.....I would do both as a set. Did both on my 90, only did the master on the 92 and noticed that the clutch engagement is not right, will be doing the slave this spring.

Concur. I suggest doing both at the same time just did mine.

I bought my clutch master cylinder from these folks at Ebay auction #360224585374
The part was made in the UK. Works great and a good price. I would ask them if they have any more. Daryll

How much of a pain is it to get to the rod thats connected to the pedal?

actually not as bad as you would think. I don't even have to lay down to get it. The rod has an eye that goes over the pedal's stud and the locking clip holds it in place. I usually just reach up the pedal arm till I get to the rod & feel around for the clip. I guess the first time it helps to see it, but the clip has a tab that comes off of the circle and goes over the middle. Just find the edge of the tab and push up and it unlocks and slide the clip sideways and the clip comes off in your hand and the rod is free.

The knee bolster has to come down, mind the wires to the ALDL and the foot well light as they are a bit short. I usually get all the screws out, 7mm bolt heads, drop the panel and then take out the bolt for the ALDL, and then pull the connector on the light. I don't remember how many 7mm bolts in the bolster, maybe 7 I think. There are three up at the wrap around part by the side of the bolster, they hide in the fuzzy carpet. Three more on the face just under the dash edge, and one down in the very end where it turns from carpet to plastic, that one is in a recess and is almost centered in the panel. I pretty sure they are all 7mm heads. It's been a while, sorry. I'll get to do this, again, as soon as my set arrives from rockauto.

What Tom said. Anything under the Hush panel areas of either side of the beast in short, is always going to be a pain or a PITA if you prefer. Its not required but I would suggest pulling the seat makes life a whole lot easier to work under there. 4 Nuts, couple of harness plugs and you have plenty of room under there to work. Well plenty is subjective you have "more" room to work under there

Would these work from thepartsladi?
And...what is difference between the Clutch Slave new and Clutch Slave new cast version besides $115?

Daryll: Which Clutch Slave did you end up with..the expensive one or the "less expensive" one?

They are Single cast metal (one piece) instead of press molded together. Usually I suggest OEM on these type of replacement parts but the GM slave Master Cylinder has a very high failure rate out of the box. Much like the secondary throttle actuators.

Bill B the ZFDOC.COM posted up information on the website on these bad slave cylinders . The rubber internal plungers are either installed backwards or crimped off.

I was happy to find a vendor who sold a new clutch master cylinder from the UK. Im not sure of anybody who is running these Single cast cylinders yet

Id look everywhere before I bought anything from thepartsladi again but I do like there guarantee,find a part elsewhere for a cheaper price and we will TRY and beat it.Best price so far for AC Delco is $58 for the master and $80 for the slave but Ive only just now starting looking into this.
