Well here was the issue complete failure of the Master....rod came completely out:

LGAFF · 08-18-2014

You need....

took about an hour....
10MM socket
13MM Socket
13MM line wrench
7MM Socket
Phillips Screwdriver(small)
Extensions
Torx head set up to 30 Torx

LGAFF · 08-18-2014

*Loosen the 10mm nuts on the ECM....place to the side..
Master is under the ECM

*Remove the ECM bracket: unbolt the 10MM bolt to the cross brace, unplug the MAP sensor

*Remove the battery (Torx heads and 10MM socket to lower fender/battery cover) 13mm for hold down behind battery(don't forget the 10mm bolt on the top of the panel....its covered by a piece of weatherstripping)

This will allow access to the master

The Master is held on with two 13mm bolts that feed through the fire wall....

First remove the hydraulic line from the master

The outside bolt is easy to access with the battery removed

The second you will need to feed a few extensions with a swivel through to get to the bolt..

inside the car, remove the lower panel

Two 7mm bolts on the front

Two screws on the side....and some underneath

Once inside slide under the panel with a light....to the upper left you will see the master, the only thing holding it on is a clip

The clip is difficult to remove and put on....however its easy if you use a flat blade screw driver to gently open it while pulling it back

Master is out...reverse the process....add fluid pump clutch bleed. Not bad!

Excellent writeup, Lee!

anybody have some of those *&^%$#@!!! clips laying around. when I replaced the master on the LSV mine was taken by the goat legged bastard

all I heard was a little "ting" when I didn't quite get it on there right

the other thing "stange" to me is that the stock part had a "spacer" and the replacement master has that cast into the base of the part

my replacement has a noticeably different feel to it (not really as good as the stock one)

I'm tempted to rebuild the stocker and put it back on.

Ron,
