I recently drove my 1998 SLS 6,200 miles on a cross-country journey. About 1,000 miles in, the brake pedal hit the floor -- not in a busted line way, but in a master cylinder died kind of way. Slowly would depress to the floor every time you broke, but would stop the car. You could pump them, but at a stop sign you could get it all the way to the floor. I didn't have the right tools to do the job, so I had a shop install a new master. It worked great for another couple thousand miles, and then did the same. I took all the tires off and did a full bleed. Worked, but again, a few thousand miles, and they went to the floor. I drove them that way from Los Angeles to Seattle. Bled them a few times, but it would only last a few hundred miles. Oddly, sometimes they work great, and sometimes they don't. Do you think the new master was improperly bench bled -- its a reman. Should I get a new one, do the whole job over myself, or may I possibly be looking at an ABS problem? I don't think it's mildly connected, but I was also rocking the c1281,c1283,1287,1288 codes and had to replace the steering sensor along the way.
I was coming to the same conclusion. The reman also used the factory reservoir. Is that a general problem spot, or is using the old res okay? Somehow, at NAPA, the one with the new reservoir is so much more expensive. My only other question is, I've read that some people bleed the ABS unit while they bleed the brake system...is that a necessary step? I've bled many brake systems, but I've never had to bleed an ABS unit before.
