ISSUE DESCRIPTION

Description of the issue: After startup, release of the parking brake and commencement of taxi, the wheel brakes do not appear to function at all. I first found this with the FSW Lear 35a, then disabled all addons and reproduced the same problem with the Longitude. Hydraulic pressure was evident in the systems pages when the pedal brakes were pushed, but neither pedal brakes nor parking brakes would slow the plane. Verified by trying to also use the keyboard bind for the brakes and they also did not work.

FREQUENCY OF ISSUE

How often does this occur for you: 100%

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:

  1. Started at LQTZ, parking or runway. Complete walkaround and start-up if starting C&D.

  2. Release the parking brake and commence taxi.

  3. Attempt to stop with pedal brakes or parking brake.

Same issue on SAAB 340. Brake pedal moves in sim but no brake action is seen, I.e. there is no slowdown of aircraft.

Experienced the same - I did get a brake temp warning in the Longitude after several hundred yards of braking so I feel like the sim is registering something but certainly not enough force to actually slow/stop the aircraft.

for me this doesn’t occur with all aircraft. The default 172…no brakes…..FSW 414….brakes work fine. weird issue

SU 4 Beta - 1.6.3.0

Longitude brakes are not working.

Seem to recall no issues with the Fenix or Ini 350 last night. Will pay closer attention tonight.

Yeah! No issue with Fenix, I can confirm.

i think this is due to the legacy hydraulic system failing catastrophically in this update, I had the same issue on the dc designs Concorde, the BRAKE FAIL light was on, and all hydraulics were dead, so I checked other aircraft using the new system (737max) and they were normal, and after I wrote a new system for the concorde it also behaved normally

That would explain why the hydraulic warning lamp is now on permanently in the SAAB 340 as well as no working brakes. I wonder if a more general bug report on the hydraulics would be beneficial?

The Boeing 747 also doesn’t have working brakes. (Hydraulic Failure)

I don’t know.

The Longitude shows the Hydraulic System as being normal, I guess.

In the Saab 340 the hydraulic pressure starts normal (and the brakes work) but after a few minutes the pressure drops to zero and the brakes no longer work. This is new to su4b.

This is happening to all the planes I’ve flown today. Typhoon and F16. Brakes and parking brake work at start off, after landing from flight neither work.

Thank you for the bug report.

We have created an internal ticket to see if our team already has this logged, and if not they will attempt to reproduce the issue and create a new bug report. This item is now marked as feedback-logged. If there is an existing bug report or one is created, we will move this thread to bug-logged.

Have tried multiple aircraft now brakes work on first runway till take off then on landing nothing

Test was do an abort run on runway to see if brakes worked yay on load in runway

Take off and fly to runway 8km away and land has no brakes at all and screams into tree at end of runway

Same issue in the Aermacchi MB-339 but not in any of the GA I’ve flown.

I had no braking in the A400M

So after the update to the add-on support this morning it now seems to work with the aircraft I was having no brakes with

Same issue encountered here on both Boeing 7477 and SAAB 340

Had brake failure on AzurPoly’s OV-10 Bronco last night.
