Hi guys,
Back with another question... Maybe I should just open a single thread for all things related here lol
The other day while riding I noticed my front brakes were getting spongy (ok, really spongy). If I gave the lever a hard pull, I could bring it all the way back to the grips.
Knowing the previous owner never did more than replace the pads on these brakes, I've opted to do a full rebuild of my front brakes. The brake line is the rubber OEM line from about 20 years ago and by the look of the caliper seals, they're probably about as old. I just cleaned up the caliper and pistons and replaced the seals. My master cylinder rebuild kit and new front brake line are coming in on Wednesday (there was a mixup at the shop killed my riding for the weekend).
Anyway, I was thinking about this problem: I've never bled a dry line Anyone have any tips on this? I did run out and buy a hand-powered vacuum pump for the job, but I'm wondering if I should be doing anything else? Do I need to pay any special attention to bleeding the master or basically make sure the reservoir stays full and pump away?
I have changed the brake fluid before using the traditional crack and slow lever pump method, but I never let the reservoir get too low. Now that there is air in the system, just want to make sure there is anything special I should be doing.
Thanks!
**EDIT:** I've also read quite a few things about bleeding bottom up. Is this better than using the vacuum pump to bleed down? Anyone have experience to compare the two methods?
