weird noise

Allways happy to help
When you say the noise occures when pulling away is this first thing in the morning ?
could be the pistons are sticking and keeping the pads in contact with the disc over night, the metal sintering in the pads rust slightly sticking them to the disc and a clunk can be heard as you pull away and the pads disengage.
I'm noy sure this is common on Freelanders but I know my XJR 1300 yam sufferes badly from this in wet weather

Hi Edge.

The sypmtoms I experience of the brakes is that when cold they seem ok. When the car is warm or have been in a journey say for 20 mins or so, they could grind sounding as if the pad is worn intermitantly. Also when warm or in 20 mins journey, I can hear clicking noise either just coming to a stand still or when I pull away from stand still it also clicks. Again not all the time.

Can I just check, the slider pins are the ones with the black springy rubbers at the end. They just pull out. I know they need to be greased/copper slip. But cant seem to get the movement in the pad solved.

Cheers

OK so.... the problem could be that the pads are rubbing ever so lightly and as they heat up during driving the heat is passed to the pistons /fluid causing a expansion that pushes the pads on /grind.
if the pistons are rusty or dirty round the outer edge they wont draw back enough to allow the pads to come back off the disc .
Try cleaning off the crap,a toothbrush( use sombody elses ) and washing up liquid is good and spray with WD40 or somthing like that and using your fingers and thumbs push the pistons back into the caliper dont be tempted to use Mole Grips, plumbers pipe wrench etc as you may damage the chrome plating and cause a seal failure
push them in and out till it frees them up then copper grease everything .

Just had a thought
if the ledge on the caliper that the pad sit on is rusty wire brush it and grease it this will allow the pad to slide across it smoothly

could be cheapo pads.

Re: Brake Pads
If you have to push the pistons back to get the new pads in - open the bleed nipples to let the fluid out as you push them in.
Means a quick bleed after changing the pads BUT some have pushed dirt back into the ABS valve and had an expensive repair to get it all fixed afterwards!
Not worth the risk!!


Posted this on last brake thread, seems apprpriate here too - if it ain't the cause of the problem - take care not to create an even worse one.

Cheers Guys,

Will have to sort out when snow is gone. The pads and discs are Pagid. So not very low budget ones. Tried a few and all been crap. Just need to sort out as its little frustrating. Changed pads and discs twice in a year as the last pair were crap.

hi there,

Managed to check the pads. I changed pads again! Check the piston in the caliper and cleaned any crap that was present. As you guys suggested. Cleaned and copper greased the slider pins and put a fresh set of pads! Did not check the brass bits that hold the pads in place on the right caliper and still knocking in that area! When pulling away. How do i make sure there is no movement in the pads? Is there something I am missing or apart?

When I changed and cleaned first journey there was no knocking. My second journey, started knocking again. Only right side!

Or can it be a bush?

Your help will be much appreciated!

Regards
Nick
