4+3 Clutch Slave Question
For all you 4+3 guys. Seems like in my 84' I'm changing the Clutch Slave Cylinder every 3 years or so.Is anyone haveing better longevity than this? Also, I'm thinking about,this time, just putting in the soft goods kit.$9.00 vs $90.00 for a complete unit.

"A year"......I wonder why...Is it the heat? using Brake fluid instead of Clutch Fluid? My 96' is original...Strange.I thought I found a Kit from Advance but I found out it was obsolete and not available as well.

I thought I found one at Advance Auto.They have 3 listed but when I went to place my order it rejected it because they couldn't get any of the 3. I have ordered a new complete one $81.00 from Advance.

You may have something here. GM Clutch Fluid,P/N: 12345347, has the correct additives etc.better lubricates the seals, extends their life and resists air entrapment better than Brake Fluid I was told.

I might wrap the Left exhaust pipe with some insulation as it is directly in front and below the Slave Cylinder.I bet heat is the culprit causing the Slaves to not last very long.I bet it would help.I don't know weather they use Buna or Viton Seals but Buna is only good for about 180 F and Viton 450F.

Well,having trouble bleeding the new slave cylinder of course. FSM says to hold the slave at a 45 degree angle with the bleeder valve pointing upwards. Anyone else have a pain in the butt time getting all the air out? Were gonna try again tonight.I remember 4 years ago, on the last replacement, it took forever.

I just replaced my master cylinder, and the Chilton's manual says the same thing about 45 degrees. I didn't do that step, and I think I got some air left in because my clutch catches about 1/2" from the floor board (very low). I'd like it to be a little higher, maybe another 1/2".
But when I open the bleed, a steady stream of fluid comes out until the pressure is relieved, no air.
When bleeding, I had my helper (The wife) pump it 20 times and hold the pedal in, bled it, and released the pedal. Filled the cup, pumped 10 times then bled, and repeated 2 more times.

"I didn't do that step, and I think I got some air left in because my clutch".
