FCCBohica Posted December 3, 2008 Share Posted December 3, 2008 During taxi, there is a vibration coming from the the MLG, both squeling and grinding. Upon insp of the brakes and tires there was no defect noted?? Just curious if anyone has run into this problem before!? All call to the experienced guys on this one!!

Steve1300 Posted December 4, 2008 Share Posted December 4, 2008 My ears are old and tired from 40 years on a flight line, but I don\'t know that I have ever been able to hear brake noise during taxi. I have heard them while towing an aircraft, though. If I were to hear noises like that on taxi, I\'d be taking all four wheels off and look for damage done to axles and such. A noise THAT loud cannot be good. Quote Link to comment Share on other sites More sharing options...
pjvr99 Posted December 4, 2008 Share Posted December 4, 2008 Vaguely remember this from the single disk B-models - if the protective paint(?) coating applied at repair/overhaul was not sanded off, brakes would make quite a lot of noise and shuddering until coating WAS eroded off by the pads ....

Muff Millen Posted December 5, 2008 Share Posted December 5, 2008 Man! wow the brake sound of the C-124 and or the KC-97 a sound that we never hear any more. Oh those good old days. Just for info sake if you have that kind of noise from a Herk I would suggest a look at the wheel bearings....something ain\'t right.

NATOPS1 Posted December 9, 2008 Share Posted December 9, 2008 If it makes noise with the brakes off BEARINGS!!! If you fly it, take a look at the MLG (AFT) as it retracts, see if you have any vibration during the retraction (do you have a nose wheel shimmy)?

C130Hcc Posted December 10, 2008 Share Posted December 10, 2008 You\'re right Muff, you could tell those KC-97\'s as soon as they landed. You didn\'t even have to look at the plane to know what landed. You could hear the thing all the way across the base. Quote Link to comment Share on other sites More sharing options...
Per-Stian Bye Posted January 12, 2009 Share Posted January 12, 2009 During taxi, there is a vibration coming from the the MLG, both squeling and grinding. Upon insp of the brakes and tires there was no defect noted?? Just curious if anyone has run into this problem before!? All call to the experienced guys on this one!! What kind of brakes do you have? I have no experience with the single disc. Howewer the multiple disc makes alot of noice nust the way it is. Keep in mind the disks are "brought" in at rotational motion by the keys inside the rim. They are NOT hold by any sort af bearing:eek:. So the brakes sound like their full of rocks just bacause the way their constructed. If it squeeks more than usual I would start to look for loose screws or loose braking pads on the actual brake. It would surprise me tha t the bearing would cause this noise.... best regards psb Quote Link to comment Share on other sites More sharing options...
Zaherk Posted January 12, 2009 Share Posted January 12, 2009 On your After flight inspection, do you feel you main wheel rim temps? A hotter than normal rim, compare to others, might indicate brakes that are binding. Also what we found with some of the multidisc brakes was that the inner disks(middle) wear faster than the outer disks. The brake still looks good but on a real close inspection the inner disks are worn to the metal, when applying brakes the whole airframe shudders with a grinding noise. Then an unlikely thing to happen but not impossible, was the correct axle spacers fitted? Regards Quote Link to comment Share on other sites More sharing options...
damnpoor Posted January 21, 2009 Share Posted January 21, 2009 Did someone change a wheel assembly recently and screw up installing the spacer or bearing? Quote Link to comment Share on other sites More sharing options...
Spectre623 Posted January 21, 2009 Share Posted January 21, 2009 (edited) Can't ever remember hearing a Herk brake squeal, lots of clanking and roaring though. I have seen the inner bearing left out during a tire change. Not a pretty picture. Were the inner bearings taken out and inspected. With the inner bearing grease seal in place it is hard to see if all the rollers are in the bearing. Bad inner bearing would side load the brake and axle big time. Sounds serious whatever you have...If it's squealing...it ain't happy!! Edited January 25, 2009 by Spectre623 Quote Link to comment Share on other sites More sharing options...
