I set off this morning on my 2006 1200 GSA with non servo brakes got about 100M down the road and noticed that the brakes were full on, which in turn made the engine feel like it was about to stall.

I turned it off, left it for a minute and the same problem when turned it back on. I pushed it back into the garage and left it.

Any one know what the problem is ?

Cheers

Hi Andy, sounds bad, but if it's a non servo bike, what could it be. Seized Pistons...

I don't know, but good luck with it.:thumb
 
Forgot to mention, I washed it on Tuesday night, and put it straight in the garage and not used again until this morning.....I don't know if that's got anything to do with it ??

Also, there was no red warning triangle on the dash when the brakes were locked on.

Cheers

Confused....? If the brakes were "full on", how on earth did you ride it, let alone push it?:)

Put it on the centre stand and try spinning the front wheel first, then the back wheel... at least you'll then start to isolate the issue. Good luck.

hi it can't be that bad if u were able to push it try each wheel first to see which one is draging and try cleaning the calliper jjh
 
You could tell the brakes were on, but I managed to limp it home.

I didn't have time to have a look at it, as I had to get de-kitted put the bike away, and jump in the car, so I wasn't late for work.

You didn't say when you last rode it. If it's been standing for sometime I would suspect seized pistons.

I last rode it on Monday morning, in torrential rain, then left it in the garage unused, I then washed it Tuesday evening, put it back into the garage and attempted to ride it to work this morning.

You could be right about seized pistons ??

Put a large screwdriver inbetween the pads at the top alongside the pad retaining pin and lever them apart.

Apply brakes then repeat the levering, do this a few times and they should free off.

If it's the rear brake push the caliper (by hand or with your foot) towards the wheel, this will spread the pads, apply brake and repeat a few times as per the front.

Once freed I guess you should push the pistions right out and clean them - is there anything else to do or are they likely to seize again unless a complete caliper service is carried out?
 
Mine did a simlar thing a few days after I'd picked it up (1 years old with 4000 miles on it)....

Rode away from home, within a mile, going along a dual carriageway the engine felt under a lot of load, de clutched, and the bike was braking...

Pulled over fearing something was seriously wrong... Up on the centre stand, front discs pretty hot, considering I hadn't applied the brakes.

After a couple of minutes, started her back up again, and the front brake was free...

Rode off, and never had a problem since.

All I can assume was some crap on the pistons from when I'd washed it, which has then moved after a few applications of the brakes and warming up and cooling down.

Hope you get it sorted... It was feckin annoying to say the least

Shoot me down here..........but......I had something similar after an accident - thought the front brakes had seized as I was pushing it on the van. However - it was the hand-protector that had slipped round (09 GSA) and fouled the brake lever.........how dumb did I feel.

Just a thought...

Thanks Steptoe :thumb I'll give this a try when I get home from work this afternoon.

It has happened to mine a few times you will probably have to to do a full strip down and clean up of the calipers i had to on my fronts,
I tried the screwdriver at the first attempt and it got me home but it happened again the next time out
Good luck
 
I suspect that if it was anything serious, you wouldn't have been able to push it. Brakes could not have been "locked on".

More likely just a thin coat of rust/muck/residue on the discs after washing it and drying out which would gradually disappear after a couple of brake applications.
 
It was seized pistons both front and rear :augie

I'll be striiping down the brakes this week to give them a good clean and also to put a bit of copper grease behind the pads as the front brakes have been squeaking.

Thanks for all the replies :thumb

Let us (me) know how the strip down goes - splitting the calipers scares the crap out of me...

That's very unusual for ALL the brakes to seize, the brakes are linked, the front lever is definitely clear of the handguard? brake light isn't on constantly is it? :augie

Errmm........it was actually the hand guard that had rotated round and was pressing against the brake lever :augie

Pretty obviuos when you actually notice it, but with the hand guard being so close to the lever, and both being black, it is actually quite easy to miss. Design of hand guards could have been a bit better......note to BMW :comfort

But there you go, leason learned :augie

I took the opportunity to remove the pads clean everything up with a soft small brass suede brush, put some red rubber grease on the pistons, and a smear of copper grease on the back of the pads, as the brakes were squeaking a bit, and just for my peace of mind.

Thanks for all the replies :thumb2
