I just installed my stainless steel brake lines, did the rear first, it turned out prefect. Next moved to the front got all the air bubbles out of the line. Problem is the front is still soft.. I checked the line and there is no air in the it, the fluid is at the correct level. I just don't understand why its still soft.

I am able to stop using the front brake but it feels like its at about 60% to 75% power of before i started messing with it.

What can i doing wrong? This is the first time i have ever bleed brakes before but the rear turned out prefect so not sure what happened up front?

Air can leak in at the banjo bolt seal washers and new pads need alot of bedding in. Mine took a few hundred miles to really bite.

Quick, dirty trick is to back bleed. Grab the wheel at 3 and 9 O'clock, push the caliper SLOWLY with your knee. It will force the fluid up to the master and usually any trapped ait too. Be ready to clean it up if you let it overflow, or take some fluid out of the master first.

Works on the rear too.

make sure a piston in the calliper isnt sticking. you can use a vacuum pump to pull the fluid thru from the calliper. you can buy one on ebay for about $50 or get a 25cc syringe and some rubber tube and small zip tie. put one enf ot eh tube over the bleeder nipple and small zip tie to hold it in place, not too tight and attach other end of tube say about 1 inch of it to the syringe. use the syringe to suck fluid thru.

hope this makes sense

Rubber hoses will swell under pressure allowing some of the force from the lever to be lost before it reaches the brake pads. SS brake hoses are wrapped with braids of wire, basically, to minimize swelling. This causes much more of the lever force to be transferred to the brake pads.

The result to you is firmer brake lever feel, as the connection is more solid, and more power from the brake from every lb of force you pull the lever with. Not as much force is wasted in the swelling of the hose.

Mine is not abs but my thoughts with abs, is any brake upgrades needed? You can just grab with a death grip every time and it won't stop any faster will it?

Just never had abs on a bike before, and never upgraded lines on an abs car to know..

If u engage abs in a car it will have a chatter feel (lock,roll,lock,roll,lock) until u let up or modulate the brake. Dunno if that is the way on a bike, but the technology must be the same. If it is, itd be pretty unnerving to lock the front. Best be would be get comfy w/panic stopping whether you have abs or not.

Just with abs if you drain the fluid you get air stuck in the abs and you have to purge it out by.activating the abs then bleed the brake again! But you don't have this issue!
Personally I think someone with enough skills can brake faster without abs but it will save you from a lock up under panic braking!

you just hit the nail right on the head with that statement

im still alive today cos in about 2004 the abs on my k1200RS saved my life from being run over by a moron cage driver who drove straight thru an intersection and if didnt slam the brakes on as hard as i did and serve i would have been killed for sure, the abs got a work out on that occasion i assure you.

Yep. That is why he asked if you had ABS. Sometimes when I bleed the brakes in my car they do feel a bit soft but after tripping the ABS under hard braking it gets better.

If there was no air in the lines I'm not sure what caused the brakes to be mushy. At least its fixed now. Which lines did you get/?

On place to check also is at all the Banjo bolts. Sometimes bubbles like to hide in there, but good the hear you got the sorted.
