You heard me!
I've tried a zillion different ways to try to bleed my brake lines to get that nice rock solid feel at the brake lever. None of them worked to my complete satisfaction.
Here is my trick that I've been doing:
-Take the cover off of your brake fluid reservoir.
-Take off your right side(throttle side) caliper and press all the pistons all the way in. You will send any air bubble right up the line to the reservoir.
-Put the right side caliper back, you don't need to torque the mounting bolts to 28 lbs-ft yet as you are gonna take it off once more. Just tighten it mildy to get in in place.
-Now squeeze the brake lever a few times to take up the caliper travel so the pads are in contact the rotors. You are filling the line with pure brake fluid with no chance for air to get back in.
-Now undo the left side caliper(clutch lever side) and do the same. Press all the pistons in and it will send any bubbles accross the line and into the left side caliper(and most likely beyond it up towards the reservoir).
-place a piece of wood (plywood maybe?)in the left side caliper so the pistons can't come back out for the moment.
-Don't remount the left caliper yet.
-Now take off the right side caliper again and press in all the pistons again.
-Now remount both calipers... be a good boy/girl.... use a torque wrench at 28lbs-ft.
-squeeze the lever a number of times to refill both calipers with bubble free brake fluid.
If you don't see air bubbles come out of your system at the reservoir, you can call me a monkey!
Your brake lever will feel as solid as a anything. It gives an absolute feel of control for your brakes.
No mess, no spilling brake fluid. it takes about 15 minutes to do.
Now go do it!
If you have a two line system in paralell, it works even better.
My TLR calipers are hooked in series so I have to do this whole process.
Double check your torque spec for your bike's calipers... I just said 28 lbs-ft cuz that is what mine is.
