Brak Bleeding (vacuum pump and drip method tried buttle still a little soft)
Hi all, been working on bikes for a while so not a complete nube but more of a weekend warier than a professional mechanic. Anyways I did a complete fresh fluid change this past few days (coolant, oil and brake/clutch fluid) as it was time.
I used my trusty hand vacuum pump to draw all the fluid slowly and maintaining level in the reservoir out of the brake system as I always have done making sure that the fluid never gets below the low mark and not let any air in. I close the nipple when the pressure gets low and then pump with he nipple closed as to prevent air bubbles. I also take care not to loosen the nipples more than necessary (half turn) to draw the fluid out. I felt that the hydraulic pressure or pressure to engage the bakes seemed a bit weak/spongy not terrible just not as I feel it should be.
So I tried to use my sure fire method to get any air out that must of snuck in by using the drip method. I did this for about 30 to 40 minutes and about 6 oz of more fluid (essentially flushing the system again). Well it still feels the same.
I don't have a professional brake bleeding system (although the Mityvac is very good) and was wondering how you guys do it?
My clutch and rear brake came out just fine...... BTW
