LC or LCA: DO NOT TOUCH THE REAR BRAKE ADJUST!!!

[ExploreSA]

I have three testimonies from people who adjusted the brake lever height and that resulted in the rear brakes binding. Fortunately no damage as they realised that very quick and reset.

Our LC was last week adjusted by a rental and resulted in serious damage with the disc, calliper, pads totally cooked and destroyed and also damage to the swing-arm and mudguard

As per BMW no-one except a qualified BMW technician is allowed to do any adjustment in that area. No mention is made in the Rider's Manual of adjustment to the rear brakes, only the front brake leavers.

If the position is not to your liking then other (aftermarket or BMW) parts to be installed instead

Interesting, will monitor this

Thank you for the warning.

I sourced my adjustable lever from GPS4Africa, since the original brake lever really does not work when wearing offroad boots. It's too "low", and I could not for the life of me get the rear to lock up on gravel (please keep debates out of this thread). The old oily GS had a raised section that you could hook, that the watery GS is missing dearly. So it would be useful to be able to adjust something. I wonder if the Adventure has the same issue?

This is interesting. But really, only two things are possible here:
1. The adjustment caused the rider's foot to rest too hard on the pedal, ergo binding the brake.
2. The adjustment itself caused the binding even without the rider's foot resting on the pedal, ergo design flaw?

In case #1 this would be true for any bike, not just the BMW, not so? But, would this also not happen when installing those pedals that allow a higher position for when you're meerkatting?

In case #2... well I dunno.

Interesting, nonetheless. Which is it?

2. The adjustment itself caused the binding even without the rider's foot resting on the pedal, ergo design flaw? Yes. But no design flaw. One is not supposed to do any adjustment there

Thanks. I'll go check my back pedal just for interest sake. But, why did they make it adjustable then?

It's not adjustable at the pedal. The adjustment is made elsewhere and if you are tech savvy it is clear that the adjustment is not to be undertaken by the weekend DIY expert.

Ahh, cool then. Thx

Just had a good look at the rear brake setup. The brake pedal stop against the footrest bracket, meaning it cannot be adjusted to lift it higher. Any attempt at adjustment of the brake cylinder will just make it apply the brakes more, instead of lifting the pedal.

Egg-zaki-tilly. I still don't know how the brakes were 'adjusted', can't figure it out myself. Obviously I'm not tech savvy enough to eff it up, only enough to realize where I should not mess.

Very glad I'm not the only fool when it comes to back brakes 

Fried mine on the HP.

[AntVan]

Ouch.

Exactly OomD

This pic shows the setting on a standard new LC




This one shows the setting on the adjusted bike. Clearly the rod is pushed into the master cylinder with no adjustment to the lever itself.




Bavarian has experimented on the adjustment on my request as I have a case against the rental. After adjustment, even still on the center stand, the technician could not turn the rear wheel by hand!

Case closed your Honour!!

[Manic]

Ok, so you turn it in, the lever dont go up.

So sorry, but any one with some tech savy will know the brakes will be cooked then.

Eish wena 

[AntVan]

Oh my word.

[SGB]

The only way to adjust the brake lever is to bend the outside edge of the foot piece upwards with a large screwdriver.  Or getthe Touratech lever.  Adjuating the push rod, well, live with the damage....  Daar is nie pille nie.....

As ek nou hierbo reg lees is BMW se mechanics ook in die duister hier.

At one point, I wanted to form a rubber plug that I could fit if I go offroad, and take off with onroad boots. This was negated by the correct purchase.

The correct purchase of what, AntVan? An aftermarket brake pedal? I think your rubber plug is a brilliant idea.
