My son has a 87 Diplomat that replaced the stealth that had a unfortunate encounter with a wall. Last nite, he calls me on the way home from work saying he lost his brakes. I go to meet him, and while the brakes are low, the car is drivable for me, so i limp it home. Take a peek under it, see the RR wheel cylinder is leaking. I figure I'll take off today (a January day with a temp of 60 kinda helped that decision), replace the wheel cylinder and bleed the brakes (about 1 1/2-2 hrs at most), then have the rest of the day to work on the Cuda.
As Murphy's law would dictate, of course the 2 hr wheel cylinder job took all day. First, the brake line and the bleeder screw are froze solid, so that takes awhile. get them off, then the two capscrews that hold the cylinder to the backing plate are even more frozen. Took care to use a 6 point socket, etc...still ended up rounding off the heads. Tried the hammer on a metric socket deal, no dice. Soaked em in penetrating fluid, tried again...no go. Figured i pull the axle, take off the backing plate, then have a better shot at the bolts. Pulled the rear cover off...this is a 8 1/4 rear. That means you have to remove the pinion shaft to get the "C" clips off to remove the axle. Remove the pinion shaft retaining bolt, go to remove the pinion shaft...NO way!! Turns out the pinion shaft bolt snapped off 1/2 way, locking the shaft and preventing axle removal....JUST GREAT!
Put the rear back together, figured I'd try some more things before i gave up and started looking for a new 8 1/4 rear. Somehow managed to get a chisel on the bolt heads for the wheel cylinder, and by notching the heads, was able to get another metric socket on the heads, and this time was able to get one loose. once i had one loose, just hammered the wheel cylinder back and forth to loosen the second one.
Installed new wheel cylinder, cleaned all parts, put everything back together, bled brakes and refilled rear. Not bad, turned a 2 hour job into a 7 hour adventure! Guess i can put some time on the cuda tonite after dinner. If this diplomat ever needs a axle seal, it's time for a new rear end, or a new car ! LOL
