I had a screach coming from my front brake, it hasnt been riden for a while. I asked the guys at bikemart about it and If I needed new pads. They reckoned it was just glazed over and to take the pads off and rub them on concrete and then put them back on. I had a go at it myself as the said it was piss easy. BIG MISTAKE.......took the front brake off and fluid was pissing out. Didnt disconnect any hoses or anything. SHAT myself so I put it all back together, NOW the brake doesnt work and the pads ar grinding. I made a big Boo Boo. Please help. The lever pulls all the way in with no stopping at all. How can I fix it and is it safe to ride to a bike shop tomorrow ?
