I'm going through the process of replacing all the fluids on a new-to-me 2004 with 30k miles, and I need some help fixing the rear brake. The rear brake was mushy (but functional I think) when I bought it. Here's what I've tried:
- I went to bleed with the basic method seen in this video https://youtu.be/qXHIlxfnLSI, and only got about 2" of hose filled.
- This being my first time bleeding brakes, I assumed I was screwing up and went and bought a vacuum bleeder kit. Pulling 8 psig vacuum and pumping the brake over and over for a couple of minutes, I just get bubbling from the bleed nipple. The nipple is definitely open and the reservoir cap is off.
- I was able to bleed the hose from the reservoir to the MC, so there's nothing wrong there. I pulled the bleed nipple and couldn't bleed it with an open port, it just makes a sucking sound like a straw in an empty drink when you pump the brakes.
Anyone know what problem this points to? Perhaps a blockage or a leak somewhere? Should I be rebuilding the caliper and MC and replacing the hoses anyway, and would this fix my problem? Should I just buy a complete used rear brake system off ebay?
Thanks for your responses!
