back break rubbing making nioses xantia

[CitroJim]

I feel left out, mine still have machine marks on the back, did have, now hidden with grease

Ahh but your Xantia is brand new Neil...

But the thing what i cant get my head round is. To make the piston move to unlock the caliper on the front break.
Why would i have to look at the back breaks?
I do know that the hand break operates the front. On theses citroens. Has it gt something to do with that?

Then this is probably the kit you need, and would do for both front callipers. However, please make sure that it is the right one for your Xantia;

While on this page, item BCK3308 is probably what you need, although you will need 2 kits (one per side), but it is less likely these will have failed;

EDIT; It is unlikely that the rear brakes are causing problems at the front (unless you have a problem with the hydro-pneumatics (please don't have a problem with the hydro-pneumatics!)), but as I explained, if either handbrake cable has seized (or incorrectly adjusted) then that calliper might be locked on. Have you tried taking the handbrake cable off its' calliper lever to see how the foot brake is? It could be worth a try.

You don't..

I only suggested the rear caliper problem because earlier you indicated you thought the noise was coming from the rear brakes..

Be aware that the front caliper pistons need to be wound back to enable new pads to be fitted as they have the handbrake mechanism on them. The pistons don't simply push back like conventional caliper pistons do. You need a special caliper piston rewind tool for this job. If you try to push the pistons back without winding them back you'll damage them.

Yes i thought so. My brother thought it was the front.
Yes the brake pad bolts was really hard to get off. We used pretty much the same method from the link.
So we checked the pads. Greased bolts pads caliper up. Then put it back on.
We then tested the break. With the engine running. Took the foot off the break. Tried to move the it disk wouldn't move.
Then we took it off had another play. Put it back on tested the breaks again foot on foot off. Move the disk. There was slight movement on it
My grandad reccens. Its the piston for the caliper not releasing.
When i start to break. The grinding noise is there. Slow down take my foot off the break. Then a couple of seconds after i relise the break. Its still making the grinding noise

OK, I think that some clarity here is needed. Which brakes are grinding? The title suggests front, but the rear brakes are also getting mentioned enough to cause the confusion.

[jacksun1987]

The problem started this week when i really noticed it. It has been like it for a while but not that bad. So it didn't bother me.
So what ever it is prob got worst

When the noise happens, gently pull on the hand brake slightly, not even to the first notch.
If the sound changes then it's the front brakes, if it doesn't, then the rear brakes are causing the sound.

If it's the front, with the front of the car up on axle stands, get the wheels off and unclip the ends of the hand break from the hooked arm of the callipers.
Spin the wheels and see if they are sticking. Apply the brakes, release and spin the wheels again to see if they're still binding.
If they are, then the callipers/pistons need the overhaul kit.
If they aren't, then you need new handbrake cables.

If it's the rear that's making the noise, then chances are the rear callipers have been pushed out at an angle by the limescale like build up between them and the rear arms.
Refer to the other thread on what to do about that.

thanks ill have to try the hand break thing

[CGATCX25GTITURBO]

thanks ill have to try the hand break thing

shouldn't need to BREAK anything

[jacksun1987]

Well i tryed te hanbreak niose thing. It sounded the same. So it must be the front

If pulling the handbrake made no change to the sound, then it's the rear.
Remember your handbrake applies the front brakes.

ohh ya ok thanks ill have to wait till next weekend or prob try do it tomo see what happerns

[Hell Razor5543]

Pop off a rear wheel, and take a good look at the calliper and disk from directly above. What you want to see would look something like this; [- with the [ being the calliper, and the - being the disk (this is looking at the NSR brake). However, if it looks like this; \- then you have got the known calliper corrosion issue (\ being calliper, - being disk, again on the NSR brake).
