hey gang...having trouble now that I have swapped out my brake lines and calipers. The fronts are really soft...bled them 4 or 5 times and can not get the pressure up ?

No J Dog, I am not going to use some Viagra / Cialis infused brake fluid to get the pressure up so to speak, so don't ask...:D

What could be causing this issue ? The back brakes firmed up right away, but I just can't figure out the front. All was well before I changed lines, wonder if I caused a problem by upgrading ? Would hate to buy a new master cyl if it is a small enough fix

Thoughts ? :confused:

Have you tried cracking the banjo bolt at the master? It was clutch side for me, but I had poor feel at the lever after doing some work, can't remember what exactly, but... I cracked the banjo maybe a quarter turn and pulled the lever. It spit and burped a bit then fluid streamed out clean, problem solved. Have some rags available obviously.

I second that. Had the same experience myself. If it's handy, let the bike sit overnight with the handle bars positioned so the brake res is the highest point - the air should end up there. The next morning, carefully bleed that banjo bolt.
Re-torque to 25 lb.ft.

@RIC - thanks, but what does "cracking" the bolt mean ? my Speiglers came with all new bolts ...

@J Dog - are you saying turn the wheels hard left ?

Sorry to be so literal, but I am sure you guys have forgotten more than what I know and all of this is 2nd nature for you. In that you know exactly what you mean ..but I am having a bit of trouble keeping up...that and I am a bit worried I have hosed myself

+1

The zip tie trick works for me every time. Zip tie the lever to the bar overnight and it'll be perfrect in the morning. It works on the clutch, too.

It probably wont even take a quarter turn on that banjo bolt. Don't let any brake fluid drip on anything! Very corrosive to paint.
Yes, I meant to turn the handlebars full left to get that master as high as possible.
I forgot about the ziptie, another handy trick.

Yet another reason to swap masters. I have a ZX-10 master on mine, they have a bleeder on them, makes it much easier if you have swapped lines.

And the zip tie trick works well too.
I never noticed the master doesn't have a bleeder. I'm getting ready to swap pads and do a caliper rebuild this weekend.

Also +1 on the zip tie method - although I use a small bungee cord. Same concept and results.

What year ZX-10 master cylinder are you using? Did you need anything else to make them work?
