Hi all.....

this forums greats lots of knowledge NICE !...

So after using a battered MTB for a year (and enjoying cycling) I went out and bought the a new bike....

It has hydraulic breaks (tektro agere comp) the rear one seems sticky? .. i can feel it kinda struggling its hard to describe, any one know what this might be? ... I have a free service included and have been using for the last 5 weeks with no major probs (but riding hard so that any problems that may arise will.... is this a good idea?

I bought it from Cycle kign , the brand is Canull ? any one heard of them ? I was taken in by the sales patter seems to be a ALU6061 frame with loads of low end aftermarket parts... overall seems good tho....

    Personally I would take up the free service, they will tighten everything up make it feel like new again - well depending on how long you've had the bike and how often you ride!

    I have the tektro ones as well, have you tried pumping the brake leaver repeatedly? Sometimes that can work, I had a similar problem and ended up taking the more drastic action of bleeding them, had to get a bleed kit which I think was about a tenner, its really just for the fluid and syringe. You can find lots of guides online but if your dropping it in for a service anyway might be worth just getting them to do it.

    Brakes not breaks :)

    The pistons are finely machined to side in and out of the calliper. What happens is the pistons sometimes corrode and then there is a lot more resistance to movement.

    I remember having to remove the piston from a Ford Escort brake calliper once then filing it and using a wire brush to remove all the crud and corrosion.

    Your calliper will probably need similar treatment (a strip down and rebuild)/

    Not if it's new.

    OP: take it back for the service and mention this to them. Tektro's are decent enough, they might need bleeding, that could make the brakes 'feel' like they're hard work, because the lever is spongy, so you need to press harder to grab tthe disc properly.
