Help Brake pads

[Big W's 400]

I recently bought a new set of brake pads could someone guide me on how to install them in my 400ex.? How could u fix a bent rim also

brake pads...you take brake mechanism off & take the two bolts off that holds the brakes in....you then install your nw brakes...a manual will help you do routine maintenance like this one alot....your rim problem will be best solved by throwing it away & finding another one off ebay or buying two new stronger rims ;)
