Disc Brakes Prob

[Voltageza]

Hi Guys

 

I bought my first disc brake bike 2 months ago. Did the Burger Cycle Tour this weekend. As i do not have a bicycle rack, i colapse my back seat of my car, remove the bikes wheels and put the bike in up-side-down. Drove back to George today and when i wanted to assemble my bike again, i could not get my front wheels in. The gap between the brake pads were to narrow. The one pad of the back wheel is also rubbing against the disc.

 

What happened and how do i fix it?

You can just prise the pads apart with a flat screw driver before trying to slot the disk in.

1. When you take the wheels off there is nothing to stop the pads from coming out more. This can result in bigger problems if the brake lever is pulled in by accident. You need to insert something between the pads to block any outward movement after you have removed the wheels. There are specific brake "blocks" which can be clipped into place once the wheel (disk) has been removed.

I got some from my LBS and also in the brake bleed kit from Avid or you can make your own out if you got the inclination to figure out the correct thickness and shape required.

 

 

2. The back wheel rub could be due to removing and installing the wheel with a significantly different skewer (quick release) tension or if the wheel is not in the same position in the drop outs as before.

Loosen the quick release and make sure the wheel is square before tightening the skewer just enough to make it slightly difficult to close with thumb pressure.

jip, take a flat object (knife, screw driver, flat spanner etc.) and wedge the pads open. My brakes also rub the discs every now and then, don't really know how to sort it out completely, but if it gets bad, I loosen the whole brake pad assembly and tighten it slowly while I have the wheel running. It is normally pretty good afterwards.

take a wooden peg apart, when you remove your wheel stick the peg in between the pads.
