got new brake pads fitted today on my front weel but i think the pads are rubbing agasit the disc because when i go up hills my speed drops down and when i got back home ather getting back from the garage the front disc was red and very hot. is there any way of sorting this out .

It appears the piston in the brake caliper isn't retracting and holding the pad against the disc. Take it back and have them disassemble the caliper and clean the piston and bore, brake dust can build up in there and prevent proper operation.

thank you i will do that. but only thing i find weird is when i free wheel it i dont it is sticking and when i have ridden it

As already stated above, one of the biggest problems with replacing pads is no one ever cleans the dust off the outside of the pistons. Usually you can get away with it until the pad starts to wear and pulls the seal out.Good luck.

Dust? It's usually a thick ring of embedded grime.

no the disc is fine i think. what happen is today took my bike to the garage and told them that i was having problems with my speed when i was going up hills its keeps on droping so i have to keep on droping down the gears but then if i leave it on a low gear to long it over ravs then if i but up a gear it does not go up. and i left with then and they told me it was the front bake that was on top of the disc that was slowing it down but it seems to going slower now then it did before i took it in and the front bake disc is glowing red now. but it did not do it yesterday but they did tell my my disc is ok its not brocken

the only thing that i am worried about is will it damage my engine because it is pushing hard because the brake is rubbing and i dont wont the brakes to set on fire will they

Fire won't be an issue. Once the caliper gets red hot from the friction, the seals on the pistons will fail and quench the caliper and rotor with brake fluid.

ok thanks all for your help

How old is the bike? Sometimes the return port on the handlebar mounted master cylinder gets clogged up, and the system pressurizes and puts on the brakes real slow like. You can check this by unscrewing the bleeder fitting on the caliper, and if fluid shoots out that's an indicator of a clogged return port. Or termites.
