This is adequate to fix the most common leak, but doesn't address any internal working parts. B- The rest of the seals and o-rings to do a full rebuild of the internal working components and seal the shaft leading to the car interior. C- An upgrade aluminum seal-carrier cone. This is insurance against breaking the OEM plastic cone during the seal swap.

It's old plastic and not hard to break. I figure guys will buy these and then possibly sell them along if they succeed with the seal swap into the OEM cone. Or not; given the singularity of the process, why not upgrade?

Opinions differ on the degrees of difficulty for the various facets of this job. I have only ever removed both cylinders from the car to replace any seals. The new polyurethane rear seal is a little balky, and it helps to heat it in oil before folding and manipulating it into the groove.

You need to use quite a bit of heat hot to the touch on the plastic cone to get it to soften, with a heat gun or hair dryer. I dutifully pulled everything apart and discovered a shrunken O-ring rattling around in its groove.

Replace it with the NAPA part, or tried to. Discovered that if you don't have the set screw flush with the booster bore, pushing the oversized O-ring in will nick it as it passes over the set screw hole. A new leak will ensue shortly. I recommend deburring the set screw hole prior to pressing in the new, and slightly oversized, O-ring. So, having figured that out, I reassembled the whole thing and pressurized. Now I'm getting a small leak, but I suspect it's from the front cup assembly's see red below shaft seal bushing.

Again, another washer and then finally the nut : You might notice that clamp around the nose of the cup. I lightly crimped an Oetiker 22mm clamp for provide strain support for all these operations, but in reality you probably don't need one if you proceed very carefully.

With a decent number of wrench turns, the seal is smoothly pulled from the cup nose recess. Part 1 is now complete : Installing the new seal was, frankly, a bitch. The bore is undersized and relies on the compressibility of the rubber coating to squeeze into the bore and provide a tight seal.

Max recommended sanding down the lip a bit to provide some bevel to help start the new seal into the bore. Some grit sandpaper did the trick. The socket protrudes from the cup and rests on the first shoulder inside the cup, and takes the compressive forces that the rather fragile lip might bear. On the seal side, I placed some flat shim steel to evenly distribute forces over the width of the seal.

Next I placed the seal on the bore lip, dribbled some dish soap over the seal, and wound up the vise while heating the neck of the cup with a hair dryer to provide some expansion another suggestion from Max. The seal moved smoothly into position. I had to push the seal completely home using a small socket that matched up with the O.

Again, a little force from the vise did the trick. The new seal feels much, much tighter around the plunger. We'll see if it solves the problem. Stay tuned. So, if you're getting the classic dribble from the booster weep hole, obviously you should change the O-ring.Power brake master cylinder and booster repair kit for Bendix power brakes.
