X-brake - annoying noise

[Saffy]

In the truck I have had a horrendously annoying mystery rattle/ rapid creaking for awhile which comes and goes, has some relation to engine load/speed/vibration.

Finally figured it might have something to do with the handbrake as it goes away when gently easing up the lever when noise happens whilst whilst driving.

PTO version of X-brake fitted on 300tdi CSW (had to replace cable type). I thought it was the cable hitting bottom of seat box as there is a contact mark -  so cable-tied it in such a way to pull it away from there but has had no effect of the noise.
I remember reading a website or forum  about annoying noise from cable and x-brake but can't seem to find that now. Anyone had this? Looking for answers before pulling things apart.

DOH! just found the x-brake instructions mention a rattle - might be one of the pads needs sticking back in with silicone.

yeh. have a look under. it could also be one of the cables knocking on the PTO. - like what happend to mine. cable tie, or a bit of adjustment...

Hi ,

Yes i have the same rattle, was very bad but stripped it glued pads in, i didn't use silicon as is not heat resistant and disc gets warm (although can not un-a-just anymore), and silicon is not resistant to brake cleaner.

Noise is now better but not solved, and to be honest is really peeing me off, so if you find a cure let me know.

I had the cable on mine rubbing on the underside of the seat box. I jammed a piece of high density foam between the cable & seat box & this solved this noise, but I've now got a new noise. I think it might be one of the pads coming loose. I'll have to strip it down & have a look.

[Landy Andy]

i found that the noise was caused by the pads, and then transferred up the cable, cable tied cable and that helped, but at 70-75mph the noise is bloody annoying, and not good as am going on a 3 thousand mile trip and this is they only noise i haven't cured.

I am not so anxious about that noise now that I know what it is and not the gear box falling apart - rocker shaft coming loose - steering ball about fly off and other such things that wander though my head when driving with mystery noise.

Though I did have a quick feel of the 'fixed' pad and it seems to be still fixed in place

I grabbed the whole x brake caliper and it rocks ever so slightly on the caliper sliders - the pads then 'dings' quite loudly against the disc . I suspect this is exactly what is happening when moving. Design fault me thinks, not wear as this thing is less than 500 miles old!

[Landy Andy]

Mine is also quite new, and i know the fixed pad is well and truly fixed but still get the noise, like you say "design fault".

I will be spending a few hours under my truck this weekend, and if i find a cure i will let you know.

 seem a few of these ( mainly on comp vehicles) that have bent the plate, causing run out and uneven wear,distorted/overheated discs ect, i am not knocking the item as the ones i have seen have been mistreated and even a full bore launch with the handbrake still on  :shock:

  Just a idea if it has had  a clout ???

[Landy Andy]

Not had it long enough to see any action, being carefull at mo with trip planned.

no sign of a clout on mine either - protector bracket still virginal - and my winch PTO thingie hangs lower. I suppose I could put a dial tester on it and check for wobble ... sometime.

[Landy Andy]

Just what i thought of!

But where do you get dial tester from???

is yours worse at higher revs?

kicks in at different rev ranges, only when moving, usually on acceleration - noise is same level for slow or fast vehicle speed.

erm dial indicator - not sure- I probably nicked mine from somewhere when I was apprentice or my ol'man did, probably best to use one with the wheel or ball probe attachment. DINGCROFT sell a cheap one (link below)

[Landy Andy]

Yes, mine is the same, at certain revs.

I don't have a dial test indicator and don't like the idea of £45 for one job, especially when you might find that noise might only occur whilst driving.

Was wondering whether it was play in transfer box bearings, allowing disc to wobble????????

Or prop uj's or though my rears are new.

Nice website saved that in my favourites.

 a polite call to simon @ x eng ??  met and chatted on a few occasions now, seems nice enough guy

we have that type of brake on jcb machines and pad rattle is a common thing with them, we very often have the calipers off and just stick the thinner pad into the housing using either silicon type sealant or similar, its also common for the caliper to float on its slider pins on the versions which dont have orings on the slider pins which then means they chatter against the brake disc, if the pad is chattering against the disc you usually find it wears unevenly as it leans on the disc when running

good info - I think it's a case of chatter for me.

[Landy Andy]

yes, chatter for me too.

[clairedave]

will check mine as it also has started to rattle ,i put some foam pipe lag on cable works a treat .stop banging on seat box
