  1. Let's play trials doctor.

    Symptoms: Extremely squishy rear brake lever. With TPA set nearly all the way in (lever all the way out), when the pads contact the disc you can still pull the lever (with some effort, mind you) all the way to the bar with one finger. My front brake is much more firm and you cannot do this.

    Measures Taken: Initial thought was that I needed a good bleed. I did this, put everything back together, and the lever was still squishy. Thought I may have screwed up the bleed so I did it again, this time being extremely focused and watching what was happening. What I found was that after 150ml of fluid went through the system (refilling the reservoir a good 50 times) there were one or two small bubbles coming out of the brake caliper each time I opened the bleed valve and pumped the lever. I kept going and going thinking that at some point I would stop getting these small bubbles but I never did, they just kept appearing. I put everything back together, rolled the reservoir diaphram in as you're supposed to, and figured that I must have at least improved the lever feel a bit, as I did get a decent amount of bubbles out. Nope. I'm fairly certain it is even more squishy now than before the bleed. I am fairly confident I did a good job bleeding as I took my time and watched what I was doing very closely. The fact that one or two bubbles came out in very consistant manner makes me think there could be a leak in the system somewhere. Did some research and read that if the pads aren't contacting evenly it can cause squishiness at the lever. I checked and they seem to be contacting fine. Even when both pads are fully clamped on the disc you can still squeeze the lever into the bar. This leads me to believe there is a crap ton of air entering the system I just don't know where and I don't know what to do.

    Additional info: One of the screws in the reservoir cap is stripped. The other screw does all the work holding the cap down over the diaphram. I'm not quite sure if this could have anything to do with it, as when bleeding the cap is obviously off completely and the bubbles are appearing anyway. Also, when pulling the lever you can hear a squishing noise. I don't really think it is anything, I think it's just the rod boot with some spilled brake fluid on it making noise. Figured I would mention everything I've got though in (hope)s someone can help me.

    Diagnoses: ????????

    Cheers, sorry if that's a bit much to read through, I appreciate any help you can give me.

  2. great job, dumb question but im struggling with this have been for a while do you let go of the brakes when kicking the pedals? and if you do is it for the duration of the whole kick or what? i just keep throwing myself backward and landing on my ass

    Yeah mate same with the "wheelie stops". What you should do is apply some pressure to the pedals, then let off the back brake. This way, you already have pressure on the pedals so if you are on an incline or something the bike won't roll back. Leave the brake off until you either land the pedal kick or start getting off balance in a wheelie stop

    So to make it simple the steps are.

    1. Rear wheel hops. Brake ON.

    2. Lower front wheel. Preload body. Pressure to pedals.

    3. Brake OFF and simultaneously throw hips and body forward.

    4. Brake ON. Absorb landing with body and prepare for next move.

    * Notice I only say "brake". A lot of people, including myself, get into the habit of locking both brakes. It isn't a good habit and you should try to only use the back brake. It will help you in the future.

    Any other questions be sure to ask.

  3. They're not even EU pallets. They are the thin ones. It's probably about 5/6 in height.

    Good though, looked smooth.

    :giggle: Does not comply with international pallet standards! No record!

    Anyway, that looked sweet. I wish I could do that.

  4. From your description what I gather is that you have trouble balancing on the back wheel. If you don't know how to rear wheel hop you should do that first. That will get you a really good start to pedal kicks. This is how I learned and it seemed to work well for me. Learning the pedal kick part is simple once you have put in a lot of practice balancing and hopping on the rear wheel.

  5. It is helpful to start, but try not to make it a habit. Maybe just use it until you get a feel for where your balance should be on the back wheel, but then try another way.

    The endo technique is good when you're starting off. Later, you can do away with the endo and go for just pulling back.

    :blink:

  6. Just want to throw this out there. Maybe you could get a bunch of business cards printed with your information. Rather than waiting for people to hire you, go out to different events and take lots of pictures. Kids events especially, because parents like pictures of their kids. Look professional, and then approach people and let them know that you've been taking pictures and give them your business card. If they want to purchase a picture then great, and if not you will still be getting your name out there. (also, you might update your website to hold photos from each event so that the people can view the ones they might like to purchase)

    This may or may not be of any help at all, but I figured I would share. I am a similar young photographer and have contemplated different ways to make $$$ from it.

  7. Hey mate,

    It took me a very long time to get the hang of wheel hops. I think they are so hard because its the first time you have to really try balancing on the rear wheel. I'm not sure I can give any specific tips. But here is one of my videos from when I was learning. Maybe watching how I do it could help? Don't give up, you will get it soon.

    Also, I don't recommend doing the endo to back wheel thing. It is helpful to start, but try not to make it a habit. Think of all the situations in the future where you won't be able to do that. Maybe just use it until you get a feel for where your balance should be on the back wheel, but then try another way.

  8. I know everyone has seen it, but this is an awesome pic of Ali C, it would be great to get it with no-one in the background, like really early on a summer morning

    Wish granted. Except for the people in the windows, but you can't really see them anyway.
