Wheel Cam Lock On Grandson's Bike; Getting Tire Past Brake Pads ?
Hello,
My Grandson got a new bike, and thought I'd ask you experts some questions that have come up. I have to admit I know nothing about "bike mechanics," and would be most grateful for the help. Regarding the cam-lock that holds the wheel to the fork: Clever gadget. But, the only way it seems to take the wheel completely off is to deflate it. Otherwise, we can't get it passed the brake pads. Are the brake pads, in their relaxed position, supposed to be wide enough to allow the tire to be passed thru them, easily ? Or,...? Any thoughts on, or links with pix that show how to, would be most appreciated. Thanks, Bob |

Thanks, Bob I thought someone had asked this question before but: If it has Vee brakes: http://tinyurl.com/nx3skot it has a sort of latch just next to the noodle that releases the brake cable to allow the brakes to open wider. If it is a slightly up-market caliper brake: http://tinyurl.com/mqequ27 it will have a small cam sort of device to release cable tension and allow the brakes to open. If it is a cheaper brake: http://tinyurl.com/m8usdo2 it won't have any cable release and you may have to loosen the cable clamp bolt to change a tire. The brake blocks are usually fairly close to the rim when riding. I adjust my brakes so that the brake lever is about half closed when the brake blocks clamp onto the rim. -- Cheers, John B. |

If the braking system is set up properly the tire will usually not clear until rel;eased. Describing the bicycle or brake will get you better advice or do an image search for 'bicycle brake release'. https://duckduckgo.com/?q=bicycle+br...ax=1&ia=images For children's sidewalk bicycles or low-end adult models, remove the brake shoe on the not-cable side. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

Any thoughts on, or links with pix that show how to, would be most appreciated. Thanks, Bob The brakes usually have a method for removing the cable from the bracket on the brake, such that the brake pads can then spread REALLY wide apart and avoid the need to deflate the tire. Different brakes in the past used different methods, so just guessing isn't really an answer. If you can link to a good photo of the brakes, or provide the bicycle brand and model, people may be able to offer better help. |

Any thoughts on, or links with pix that show how to, would be most appreciated. Thanks, Bob Besides all the other comments, you may still experience a problem if the tire is fully inflated off the mounting. You would normally inflate the tire to full pressure off of the bike to seat the tire on the rim properly and then deflate it until it's pretty soft so that it will have minimal difficulty pushing it through the calipers. Then you inflate it no more than the tire pressure recommended and printed on the sidewall of the tire. Tire pressure should be no less than 25% under max pressure. |

Is it the one with a cable running from one side to the other, with the apply cable pulling it up in the middle? If so, one end of the "saddle" cable has a "trigger" or handle on it to unhook it from the brake arm, allowing the pads to fully retract from the wheel. |

I have yet to have to let air out of any of my bicycle tires in order to get it back on the bicycle. The quick release at the brake caliper or on the brake lever allows the fully inflated tire to go past the brake shoes. Cheers |

On my wife's hybrid you have to disengage the brake cable. I think the OP is just asking how to do it but he isn't saying which brakes he has. |
