Re: [Amc-list] Power brakes to manual brakes on 81 Concord - couplequestions

Is your car a 6-cylinder??   Before you go to all that trouble swapping
to manual brakes, have your parts guys look you up a clutch cylinder for
an '81 Eagle.   That will be the remote-reservoir version.  The AMC
parts books show all AMC passenger cars from 1980 thru 1983 to be the
same clutch cylinder and rod IF your car is a 6-cylinder.   They may
give you 2 choices with different bore diameters; just choose the one
with the bore size closest to your old one.   We Eagle owners have no
trouble getting these remote-reservoir cylinders -- I think their parts
book is just incorrect for the Concord model.

Hey gang, 

    I have finally got around to moving on the 81 Concord, which has a
bad clutch master cylinder and slave cylinder. 

    I got the slave cylinder just fine, but the remote reservoir style
of clutch master cylinder is no longer available. Everyone seems only to
have the kind with the reservoir attached.

    It looks like that style, which I have already bought, will work
fine on my car, with one modification. The clutch master cylinder is
right under the brake booster, and that means that if I remove the brake
booster and convert the car to manual brakes, it should all fit. 

    I checked and found that the master cylinder is the same part for
power brakes and manual brakes, so I should be OK there.

    I found how to remove the booster (4 studs go through the firewall
and the nuts are inside under the dash behind the brake pedal), so that
should be fine.

    Now, the 2 points I could not find anywhere:

1) The push rod which bolts up to the pedal - is that the same for
manual and power brakes, or do I need to hunt one down?

2) The mounting point for the master cylnder. The cylinder itself has
only
2 bolts, where the booster has 4 bolts. Are there 2 which I would use
for mounting the cylinder? Do I need to get some kind of mounting plate
to provide the 2 bolts/studs?

   The brake lines on my cylinder mount on the fender side. Does anyone
have a car of a similar vintage with manual brakes, and if so, can you
confirm that your master cylinder has the brake lines connecting on the
fender side? I checked on an 82 Eagle and on an 84 Eagle and those both
have a different booster (thicker but smaller diameter) and the master
cylinder connects to the brake lines on the engine side. 

Thanks!

Jim
