Hi all,

I am new to m-biking and have recently bought a Marin Bobcat with Cable discs.

I have only had it a week and today I went to Swinley forest (very wet!).

When coming out of the forest I noticed suddenly that my rear brake lever had a lot more play, as in the lever is coming up and touching the handle grip with very little braking being applied (enough to stop the rear wheel but not with me ON the bike).

I have checked allth obvious stuff the the cable is intact, and looks like its doing its job and I cannot see whats happened.

I can take it back to the shopbut only want to if I really have to as I am sure its something minor.

Can anyone offer any advice as to what this might be?

Thanks

Paul

Just a very quick thing to check, has the cable slipped at the rear where it meets the brake housing, could the cable locking nut be slightly loose, thus you are not getting full cable tension.

Don't know if this site may be of any use............

I'll have a look at these links though, thanks for replying

If the fronts all right, then take the pads out of the front and put them in the back and see what happens, maybe, just maybe it's something as simple as that............

Biggest problem with the mechanical type system is the inside pad has to be adjusted manual or otherwise it will only operate with one pad and will try to bend/push the dish in to meet the other pad.

I only got the bike last week and have not even done 50 miles yet. Is this likely to happen after so few miles?

I will check this out....

Thanks again

Paul

Paul, I'd recommend taking the bike back to the shop and telling them the problem.

They should have a look at it and rectify the problem no charge, and let you know what has been the problem.

If they tried to charge you, I'm sure if they're reputable the wouldn't, then I'd go along the route of the bike was not fit for purpose, surely the brake shouldn't fail so much after 1 weeks moderate use, etc., etc.


However, just to put things into perspective, I fitted a new set of brakes to the front of my TFI bike before this ride.

http://www.mtbe.co.uk/october-forum-ride-report-and-pictures-t1171.htm l

They were shimano LX canti's, by the end of this ride, about 13 mile in total, they were totally wrecked due to the muddy, pasty, gritty conditions, and some of the guy's who were using disc brakes were reporting extreme pad wear too.

Don't forget to let us know what happens, whatever you do Wink

Some great pics there mate. Looks like a fantastic place.

I thought about this today and figured I'd best take it back to the shop rather than start having a go myself, not knowing what I am doing.

In a few months, yes, but not after a week.

I called them earlier on and the chap told me to bring it in. I got it from Cycle surgery in Chertsey.

I will post how it goes and what it was etc.

Thanks to all for the help and info.

Paul.

Called Cycle Surgery last week and they said to bring it in. He turned it round in twenty minutes and it was as good as new. Cable had stretched and just needed adjusting up. Needs to go in for the first service in four weeks or so to tighten the cables etc.

Great result.

Thanks for all the replies.

Paul.

Thought it would be something along the lines of cable tension, glad it's all sorted, now get out and enjoy Wink
