have a 2017 f3 limited,took off the frame bars and had them painted,at the same tim I pulled the rear tire and had a new one put on.Also changed the rear brakes pads,put it all back together after watching many videos and I have no brake pressure.One video said to pump up brakes before turning on parking brake,dont think I did that,as of now I have no brake pressure,any thoughts would be appreciated

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
no brakes,any thoughts

Have you tried pumping the brake pedal? The brakes needed to be pumped so that the rear brake caliper piston extends out to seat against the new brake pads. I am not talking about bleeding the brakes. Just pumping the pedal a few times to see if it gets hard.
It sounds awfully much like the new rear brake pads aren't grabbing the disc, so all the pedal travel is going into fruitlessly trying to get them to close on the disc?!? :dontknow:
Are you sure the rear caliper went back on properly?? Maybe check to make sure you have a pad on each side of the disc, & not both of them on the one side.... Cos it's probably something odd like that, or you've got a bigger issue further up the (brake) line somewhere?!

Definitely sounds like we are missing something here. If you did not take apart any brake lines or open any bleeders. And you did not change out the brake fluid in such a way as to introduce air into the system. And you did not press the brake peddle with the caliper(s) removed. Then there should be no air in the system. It doesn't just sneak in somehow. Even if there were air in the system. You should be able to pump your brakes quickly and get some additional, though temporary, resistance at the peddle. I don't think it possible to crush or crimp a brake line on the Spyder.
Did you re-assemble the parking brake system correctly? Does it need to be adjusted?
It will be interesting to find out what the problem is on this one.
You only need BUDS to bleed the ABS portion of the brake system. Typically, for a simple air in the lines issue, you don't need BUDS.

I have not yet had the pleasure of doing this task, but it is my understanding that you can bleed the brakes without using BUDS. I have gotten the impression that BUDS is necessary to cycle the ABS system so that brake fluid will go through there, too. If you are doing a fluid change and don't use BUDS, there will be a very small amount of the old fluid left in the system. I have no idea what percentage that might be, but I get the impression it's rather small.
Go ahead and bleed the system as you have done your 2-wheelers in the past. Since the bike was not run and the ABS was not triggered, there should be no air in the ABS part of the system, so a 'standard' bleed process should be just fine.
.
Nope, not a good idea, and not necessary. Opening a bleed valve runs the risk of introducing a bit of air into the system. All the fluid will return to the
master cylinder, just make sure it isn't in danger of becoming over full.
But I have to agree with BajaRon: if you didn't open any lines anywhere, there is no way for air to enter the system. You might make sure the master cylinder
piston is retracting fully. If it sticks and doesn't return, you won't have any pressure. Just a thought.
Thanks all,found the problem, when I installed the #5 brake rod to floorboard #5 position,I had made a slight wrong measurement for new brake pedal ,the bottom of the brake pedal was hitting the top of the floorboard,so got out the tools and made a new brake pedal arm,and OH YEAH,its all good at the shop

oes anyone make a longer brake rod for my 2014 RTL? It looks like another 1/2 to 3/4 inch would raise my pedal to where I'd like it to be.:dontknow: I'm pretty handy in my shop; but it would be nice to just acquire one without the work involved. (??)opcorn:

Work, what work??? I find these work-around projects fun. It's fun exercising my brain to come up with a design. It's fun seeing the design evolve into a workable piece. It's fun being able to say, "I did it and it works!" It's fun having more of ME in my bike than things purchased from others.
