First, I used this procedure (Bleeding/fluid Replacement On Linked Brakes W/abs On 6Th Generation (The Ultimate Guide) - Maintenance Guides - VFR Discussion) which is easier than the one in the book, to bleed my braking system. So now you know what I did. My problem is that while bleeding the system, I was never able to bleed to part between the SMC and the LPCV. I kept hearing a "squick" everytime I pressed the brake pedal, plus the pedal was spongy and needed 2 or 3 pumps to get hard. So I thought it was air, but then, I realized that when I open the LPCV bleeder and then press the brake pedal, there was liquid going out. I thought the SMC was broken since I think their should be no fluid going out the LPCV bleeder when I press the brake pedal, so I removed it. It looks perfect to my eye, the spring is fine and the piston looks good. Now I'm at the point of rebuilding the SMC. What should I do, do you think the piston needs to be replaced? Or I'm just awful at bleeding? What am I doing wrong? Thank you.
If you followed the directions in the link (I just did this a few weeks ago), you for sure triggered the SMC by pushing in the plunger while holding down the rear brake pedal? It's a little difficult to do solo but it is feasible. It took me a while to get this part done due to the position you are in in order to both at the same time. I will add though, I have speed bleeders installed and that made the bleed process way less difficult than I had anticipated. You might want to get someone to help you with this part or get one of those inline speed bleeders to help with this process and try it again. If you were local to me, I would come by and help you out, but ".CA" is not the same as "CA."! Good luck and keep us posted.
