Hello All,

'87 300SDL 200K

I purchased the car a few months ago and I felt the brake pedal pulsate. Shortly after that the brake pad light came on. Upon inspection I found the pads worn unevenly on the front right wheel and I thought - this is going to be easy!

So I ordered a rebuilt caliper, rotor, and brake pads. I also ordered new rubber lines for the front just because the car is 20 years old. Put them on and went to bleed the brakes.

No problems bleeding the brakes except for the right front! I got nothing with the mightyvac, then purchased a pressure bleeder. The rubber caps on the resevoir would not let me put much use much more than 10lbs of
airpressure and that did not do it (I have replaced the rubber caps since then). I then tried the "old school" method and opened the bleeder and stepped on the brake pedal - still nothing. So, last option, opened the bleeder, started the car, and stepped on the brake pedal. I had to put a lot of pressure on the pedal before I felt it "pop" and the pedal went down. Out of the bleeder was black goo..... I finished up bleeding the brakes and all seemed ok.

Well, this morning when I drove in to work the pedal started to pulsate and I have been getting some pulling to the right. I think the front right brake is acting up again and I'm betting I have some restriction in the ABS "pump" since I have replaced the rubber line. Can the pump be dismantled and cleaned or is there a way to make sure it is clean?

Or is the best option to get one off ebay (I have read they almost never go bad)? If ebay is the best option from what models/years?

Thanks!

Richard
