Question about 2008 BMW R 1200 R

1 Answer

Brakes Went and killed some time fiddling with the test dmv course yesterday. Afterwards.....I seem to be having braking problems. front brake chitters and vibrates hell out of the front end now. Only at low speed though. say ~10 and under. makes some stuttery squealing noises too. also noticed one other "symptom" If I'm coasting and turn to the left, i can hear the normal tire/asphalt whisper. To the right i hear a..... rubbing...kinda. damned hard to explain. and a slight vibration too. can't hear or feel either of those when actually using the engine. right side is where the front rotor is too. Notice nothing at all handling/weird bike wants to flop out from under me wise. Another tidbit. Front tire was a touch low. pumped that up to the right pressure. Could the right turn noise be a slightly cupped tire?

Vibrating front end under braking indicates a warped rotor or stuck piston. However, your bike is new enough this should not be an issue. Has it been dropped before? Are you noticing odd wear marks on the rotor? It should be more noticable at high speeds though, so that seems a little odd to me. Can you get the front end up somehow and spin it freely, try to pinpoint exactly where the noise is coming from. Maybe check to see if something got stuck between the brake pads and the rotor? You'll need to remove the whole caliper to do it correctly, so make sure not to squeeze the lever if you do. Once you get it back on/reinstalled (just slips over the disk) then pump the lever a few times to restore pressure to the system, otherwise your brakes won't work the first time you try.

Usually if the brake light is on all the time, it's a bad front brake light switch.
There's a little tab that the front brake lever pushes against that turns the switch off.
If this tab is broken off (usually because the front master cylinder was incorrectly reinstalled) or if it is worn down, the light stays on.

Front dic brake is locked the bike is a 1975 kawasaki kz 900 how can i unlock it to move the bike

You need to release the hydraulic pressure!
Just loosen up the bleeder nipple on the brake caliper till the fluids comes out. Re tighten it again afterwards.
You got a problem on brake master or the caliper piston. Need to overhaul the front brake system.

Hope FixYa helps you out!

How do I remove the front brake disc pads on my 2006 cs500f

12 mm wrench or socket to remove the caliper.
Once caliper off , compress the cylinders with c-clamp or big screwdriver.
Remove the pads, one at a time and take note if there is a difference between inner and outer.
Some have a pin that goes through the upper part of the pad, of course you'll have to remove the pin before the pad will come out.
Install the new pads, install pins if yours has pins, install the caliper and tighten.

NOTE: Before you test drive squeeze the front brakes severeral time to push out the calipers to the disc, otherwise when you go to stop there wont be any brakes unless you pump it back up first.
You shouldn't have to bleeed them or anything. you shouldn't have to add any brake fliud either.
Can be done in less than 1/2 hour.

Gsxr 750 brake problems.

it would seem hard for me to believe that both your front calipers would go bad at the same time.. so i would think the problems is in the brake master cylinder, its not likely, but is possible that you have contamination in the system. you may want to get this problem looked at by a mechanic.

When I use the back brake, the brake light won't come on. I have checked the switch and it appears/tests good. I have 12 volts going to the switch. The brake light works with the front brake

Replace the rear brake light switch. I've run into this before as well. When checking the switch with an ohm meter, it appears good but it will not light the rear bulb. The front brake light switch worked correctly as well. I can't explain it but replacing the switch, even though it checks good, solves the problem every time.

Front brakes jammed

If you were unwise enough to think that draining brake fluid from your front brake was anywhere near to a sensible solution to a braking problem, please take your bike to the nearest repair centre and get it fixed properly before you kill yourself or someone else, or both.
That has to be the most bone-headed solution to a braking problem I have ever heard.

Seems like front brake engaged

Is yr bike fitted with disc brakes to the front?
If yes thn you will have to overhaul the brake calipers, it seems the pistons have jammed in there probabely due to rust on it at the pitted areas.
Better still is to overhaul the brake mastercylinder too.
Good luck

I have a 03 FXDWG and the rear brake light stays on all the time. The front and back brakes are free and do not seem the be bound up. There is a sensor by the rear brake reservoir that has wires running to...

Yep, the pressure sensing switch(sensor) is probably stuck. Pull one of the wires off, the light should go out. Remove the other wire and use a DVOM set to "continuity"or a self powered test light. Touch it across the 2 wire terminals on the switch and see if the meter shows continuity or the light come on. Step on the brake, it should change.I believe the switch is part of the brake line, so the whole thing has to be replaced. If you have air in the brake lines, I have seen engine heat expand the air enough to turn on the brake light, but not apply the brakes.
