Brakes Surging when stopping
So, when i pull to a stop sign my brakes release and grab, then release and grab, then release and grab. I do not have ABS, I only have 8K miles. The pads look fine, and I can't see any issues on the rotors (but that is hard to tell) Is it air in the line? it is just the front brakes. i have an 04 V-rod. Appreciate any input you guys have.

Matt,
I have the exact same issue w/ my 04 Heritage. I went to my dealer and had them ride the bike and he said the disc is probably warped a little bit. I asked if he thought it was dangerous to ride it like that, he said no and unless it was really bothering me to just wait and have it fixed when I need a front tire.
I'm not sure how I feel about this because it (the surging) gets worse the harder I apply the front brake and I'm afraid in an emergency it could be a problem.
keep us updated if you find out for sure what is causing it.

I would think you would feel a rapid pulsating in the hand brake and foot brake when braking. Those wheels are spinning fast and you would feel the high spots as the pads are pushed open , forcing fluid back up and to the levers. When no warp you dont feel this because is smooth. I would think its possible that pads are maybe beginning to glaze or wash out when getting hot. With some pads they will brake good at first and when it reaches a certain temp will loose friction (wash out) then when cool back will regain its stopping power.
Who ever is experiancing this if you would post which pads you are using it may be an aftermarket pad your using you may see a trend with a particular pad.
Just my opinion

Have you pulled the brake calipers and checked them? Mine use to do the same thing, I pulled the calipers and found that one of the pistons was stuck on the left side caliper and there were 2 pistons on the same side on the right caliper stuck. Cleaned them real good with brake cleaner and a shoe lace. Made sure all of the pistons were extending, then put back together. Now they feel like brand new!

Probably is a warped rotor, but to be sure I would set up a dial indicator on the rotor and spin the wheel to check.

My front was doing the same so I thought warped rotor then I changed the pads and noticed the pistons were un even. Cleaned the pistons and replaced the pads and all is good. Just saying don't condem the rotor yet.
