Klunking noise

[Leroy Eckert]

I have auto slack adjusters also. It is a strange thing because the only time it happens on my bus is when I really stomp on it. Strange thing, it never happens when I let off. One would think if the front end had a problem it would happen both ways. When I get off the treadle after one of those panic stops nothing happens, no noise. Leads me to believe it is in the wheel where the brake clamps down. The front end does not seem to have any problems visually. Had it aligned, no problems. Gotta read Pappy's link.

FWIW, I've never heard any klunking noise from the brakes -- but a few things in the refrigerator sometimes klunk during a vigorous stop.

From what I have read on this thread all the wanderlodges are too old

to have automatic slack adjusters. I must admit that I adjust my

brakes a lot. If I am going to slide under the bus to check the

brakes I might as well adjust them.

Its the roller that the shoe rotates on. the roller comes with the
spring kit. the roller probably has a flat spot on it . You can change
the shoes without a spring kit so I guess you can just buy the spring
kit $9.00 per side and replace the hardware. I keep an extra set of
shoes on hand and have them relined at a place in RiversideCa called
L&M Friction they wont let me leave the shop without spring kits.

here is a link to a great tutorial pdf that does a wonderful job on
explaining every part of an airbrake system and has some fantastic
diagrams. A 'must read' for Canadian Commercial driver a 'should
read' for AirBrake CoachOwners.

https://gov.ns.ca/snsmr/rmv/licence/pdf/...manual.pdf

I cant find any written confirmation of my $9.00 brake roller
KlunkFix (googeled more hits with clunk) but the most it will cost
is $18.00 and time if you have the ability to pull a wheel, the drum
will pull over the lugs. I think the roller and bushing are the
issue and the cam may also have a flat spot?

Pete:

I do not knowwhen they started putting the auto slack adjusters on, but my 84 has them, I just replaced them all.

My 78 FC 35' make the very same noise under heavy braking. The NTSB
article refers to vehicles equipted with automatic slack adjusters.
From what I have read on this thread all the wanderlodges are too old
to have automatic slack adjusters. I must admit that I adjust my
brakes a lot. If I am going to slide under the bus to check the

Thanks Greg, I have to have an state inspection done soon. I suspect
that I will need some brake work, certainly a time to address this
klunk now that I have a lead as to what is causing it.

Take a trip to Pgh. Route 8 Exit Pa, turnpike.
Walt will fix you up at the Dinnerbell Garage, Butler Pa.
Great mechanic, fair and honest.

Had the same noise on severe stops. Read some place that by fullly
depressing the Brake pedal while standing still once a day, would do the
adjustment (if needed) and alleviate the klunking on subsequent stops.

This has worked for me.

What I said is all the Wanderlodges in this thread, ie the klunking
noise, were too old for automatic slack adjusters. I am well aware
that the newer birds have auto slack adjusters.
