Repairing Wheels and Brakes Issue

[19AB67 16]

Update after landing in CYYZ: The brakes do *not* work. 

 

What's going on? 

Next I load on the PMDG standard panels (not C&D, I know of the bug...) and check out whether the brakes work then. 

[19AB67 16]

All to no avail. I am desperate now. Shall I open a ticket? 

Shall I uninstall the 777? 

 

BTW, the brakes work fine on all other aircraft, including 737NGX.

Fix is easy, goto Ground Maintenance menu, cool brakes, replace brakes and replace tires. always works.

Hi

Same problem

Where do I find maintenance section, cool and replace the brakes first, then replace the tires ???

Hi,

For info, PMDG provide us with some very interesting documents where you can find the answers to most of this kind of questions.

Especially the introduction manual which is a must read! (Ref for your question: p130).

Definitely worth reading these before posting!

Thank You for all answers

It was verry helpfull

Hello to all. I have similar brakes problems with PMDG. All the time after landing and stop in near the end of runway I can't taxi going to the Gate. The plane stuck in runway and it won't move ahead. I see the message from EICAS. Tire Pressure and Brake Temp. I can see outside red tires as well. So, I open FMC and cool brakes and restore tires. Still Tire Pressure message.

Is there a way to prevent tires and brakes messages in order to go to the Gate?

Sometimes, I get those tire and brake message off from EICAS after FMC FS Actions. 

I am be able then to move the plane and is when I get another message, Config Flaps with annoying beep sound. I can't taxi to the Gate with that "Config Flaps" sound. So I close FSX to reload the plane for another flight. Rarely I was be able to be on the Gate without problem. Any ideas?

Try this, see if this helps.

As for the flap configuration message, if you're applying a lot of power with the flaps not in the take-off setting, that's going to happen. There's really no reason why you should be taxiing using that much power in the first place.

[Budbud 227]

What are your autobrake setting, flaps, weight and outside air temperature at landing? And do you use speedbrakes and reversers?

Also what is the thrust required during taxi out before takeoff?

Pressure and brake temperature messages come from the fuse plugs melting on the wheels resulting from an excessive braking action.

A reason for that could be that the hardware you use for the brakes is not properly calibrated.

Hello my Captain Kevin, after landing, stuck on runway, fixing tires via FMC I tried to throttle up a bit taking care do not go higher than 35 knots but didn't move at all. Applied a bit more speed the message config flaps again.

I will watch that clips I am sure will learn even more. Thanks a lot.

Autobrake 2, flaps 25 I didn't check weight and temperature. Speedbrakes armed right after flaps 1. Reversers, as soon as the plane touch ground I reduce all speed from Throttle (joystick) and press F2 and at 80 knots I press F1. Sometimes I notice the plane not braking and I apply brakes manually. I think due to manual brakes is what the tires get trouble and stuck on runway. I need to figure out in other flight.

Not higher than 35 knots.

Should I manually brake briefly like stop and go? If so, the plane will stop on the other side of runway.

I use Wingman joystick not sure if spikes are present. Soon I am going to replace it because too old.

The video I linked to was posted by Kyle, and he goes through the proper procedures of how to repair your tires after you've blown them. If you don't do this correctly, what'll happen is when you replace the tires without cooling the brakes, your tires will blow again. If that happens, you'll have a hard time trying to move the plane. Then, because you're trying to apply a lot of thrust to get the plane to move, you've likely set enough power to trigger the take-off configuration warning, and since the plane thinks you're going to take off and your flaps are retracted, you'll get that flap configuration warning.

Also, 35 knots is a speed, not a thrust setting. Thrust setting would be based off of N1.

Ok, everything normal here, shouldn't cause an overheating of the brake here but...

... this can. It's difficult to measure out the manual braking on a desktop simulator when not feeling the deceleration especially when the plane is rushing to the runway end with the fear or overrun it.

Are you using fsuipc with a script for the friction or anything else altering the friction in FSX? Unless the runway is very short (less than 2200m I would say), the aircraft should reach a taxi speed well before the end of the runway using autobrake two combined with automatic speedbrakes and reversers.

Agree... also, note that if your ground speed is decreasing and you don't have an autobrake message then they are probably working as intended.  Not having a g forces in a PC simulator means you need to look for clues that you are decelerating.

 I guess this means you are using a button on the joystick for brakes.  This doesn't work very well in the 777 because a button press is equivalent to hard braking... and hard braking is not something the 777 will tolerate for long. You should consider a set of pedals along with a quality set of throttle and stick or yoke controllers.  Regardless, look for the autobrake message because autobrake is working until it appears.  The autobrake setting of 2 works on most runways on which the 777 operates, so let it do it's thing.  Also, get the reversers deployed as soon as you land because they work best at high speeds.
