rattle over bumps

[dannydm1]

everything seems to be going wrong with the car this week,
when i go over bumps in the road, even very small ones there is a rattle that seems to me coming from the right hand side of the car, thought the exhaust was loose at first but dosnt seem to be......

it came on all at once, so wasnt a gradual thing...... any ideas people???

[dannydm1]

i dont know if this will have anything to do with it but i had ny back pads and discs changed the other day, it must have done around 80miles since then before this rattle started

have u checked the caliper nuts have been tightened up correctly,or if they have worked loose a litle bit might be worth a check but am sure someone will have the answer for u.hth

havent has the wheels of yet, prosumed it was somthing under the car....... ill gave another look tomorow when it gets light......
could damaged/broken springs cause a rattle over bumps???

[wanna veccy]

only suggest the rear calipers as they would have been loosened to remove the pads/discs.if it sound like t from the front have a quick search for radiator mounts as i believe when they get water on them they also make knocking noises.

made a new discovery this morning, it seems that if i am applying slight pressure to the brakes when going over bumps there isnt any rattle!!!

seems to be deffo coming from the back wheel which are the ones that i had the pads and discs changed on on monday.........

when you get the wheels off check that the caliper spring clips are on correctly sometimes these can be fitted on the inside and not over the top they can also be bent slightly to make them fit easier and that will cause them to rattle

went to a local garage today for them to have a look, problem now sorted.

beleive it or not - turns out that the origional garage that did my pads and discs firstly put the pads on the wrong way round (which meant i had to get a brand new set as they were nackered.

and second they didnt even put the springs back on that hold the pads in place, which was causing the rattling.

wont be going back there again!!!!!!!!!!!!!!!!!!! shocking

Get a refund from the first garage. Messing up brakes is not good.
