Bongo Fury

as described, when i press the brakes most times whilst driving, there is an audible 'clonk' like something is engaging which i dont think was there when i got the bongo 3 months back. im sure i can feel the clonk ever so slightly whn i have my foot on the floor of drivers side, off the foot rest.
brakes work fine and i cant replicate it stationary as its only after moving and it dont happen all the time.
any ideas anyone? im taking it back thursday for cam belt change, air con re gassed and a new motor and resister for the air blower as mine has gone. wanted any ideas before going to him so i can get him to have a look at it and give him an idea what it might be.

always check the spinning of the fan under the bonnet by the way. it siezes easily and then the resister burns out as it tries to feed more power to turn the fan. learnt that the other day but there was no way of knowing really, just one of those things. just went one day but now worth checking the free spinning of the fan assembly under the bonnet.

Hi,
I had something similar on a car I had once and it was worn brake pads not sliding along their guides properly.
Fairly easy to check and remedy, new pads and a wire brush and some coppaslip.
Hopr this is of help and thanks for the fan tip!

Does this 'Clonk' only occur when driving forwards having reversed and applied the brakes when going backwards?
If so try driving FORWARDS slowly, apply brakes hard, then reverse and again apply brakes hard. If you get the same clonk backwars & forewards it is merely the brake pads moving in the caliper. Perfectly normal and nothing to worry about. Honda CR-V's do it as well

I must explore this Colin as I get a clickety-clunk along those lines when I brake going forwards and after having just reversed and braked. I'm assuming its just discs re-settling themselves. Brakes are excellent in all other respects.

I don't suppose the "Clonk" is people running into the back of you, is it?

You havent got a wooden leg that could be the cause have you?

Hey I have this clonk issue too. Ive had it for about 6 months, I think it started after I changed the rear brake shoes & pads, but cant be sure. It does it 8 out of 10 times when traveling forward only. I dont need to reverse to get it to happen. I usually need to be doing over 15mph to make it happen, sometimes the noise is fairly quiet other times its pretty loud. I haven't got around to looking at it as I think its going to be difficult to replicate as I need to be doing 15mph for it to happen. Maybe I could get someone to hang out the side door while im driving? Any volunteers?

Seriously though if anyone has any ideas I would appreciate it, Ive searched the forum & this seems to be the first mention of it. Its probably nothing to worry about but it drives me nuts!

Clunk! Clunk! Clunk!

If it is not for reason I gave above, (or the pads may have been replace d without the anti-rattle springs). the only other cause I can think of is if the caliper mounting bolts are lose. Most unlikely but worth checking before you modify the front end

Ah Ha! Anti Rattle springs, are they the bits of wire or the flat plates? (The bits I threw away ) Well not exactly, the new pads were missing the plates so I guessed I no longer needed them, the pads looked slightly different anyway I figured there had been a design change.Also One of the wire springs was already missing when I came to replace them. So I only have one wire in. I guess this is also why my brakes squeak a fair bit

Any idea where I can get these parts?

I do feel a little silly now I hope this fixes it, the clunk does sound very heavy though to be something as small & simple as this. Fingers crossed

Almost certainly the pads moving in the caliper, and nothing to worry about from a safety point of view. Try Bongobits for the springs/shims if you can't put up with the noise.
