Default Jcb 520-4 brake issues

Evening all

I recently went about putting a fell set of brakes in my old 520-4 loadall . I went all out and bought everything and did all the seals whilst at it . I reassembled the axle and filled with a wet brake oil (10-30) . Much to my disappointment it's no better than before really and still makes a loud groaning noise . I've tried a few different oils suitable for oil immersed brakes but still get the same issue .

I was supplied with the brass type brake discs which were the same as what came out . I'm wondering now has anyone fitted the later paper back discs to an early machine ? With success ?

Any thoughts

Matt

I would try the oil Manitou supply for their telehandlers, it has a special additive that works very well to cure brake rumble. Iíve not any in stock at the moment so canít give you the spec at this second in time.

I've tried a few different oils from different manufacturers a . Still the same . Takes near on 40 litres so it's not cheap either

Yeah I agree it’s not a cheap job, fords often had noisy brakes and this was cured using a dose of anti-squawk additive I’m purely suggesting the oil you’ve used hasn’t a high enough content.
