Well it looks like my brake booster is going.

My brakes are getting harder and harder. This has menat booster failure in all other cars I have had.

I checked the vacuum supply line and all vacuum lines in vicinity and all looks well.

Additionally, I hear no leaks, so I have determined it is the booster. Any thoughts?

I figure the master cylinder is ok since it doesn't leak any fluid.

Any special procedures to replacing the booster?

Thanks
