Hi,
2005 TD4 owner, 100000 on the clock. 6 weeks ago I changed the front discs and 3 weeks ago I changed the pads, so all nice and new. No problems for a couple of weeks. Now here's the issue. I'm getting alot of noise/squealing when braking at low speeds, particularly under 5 mph. I've cleaned the brakes and there is no other issue at higher speeds or pulling etc. Does anyone have a view as to what could be causing this? Thanks in advance guys.

Hi I don't know much about FL1, but I have found in the past that low cost pads tend to squeal, (and give off loads of muck) could it be the case here ? I had a Mercedes which did this bought some better quality pads and it stopped.
Years ago they used to put a thin metal shim between the pad and the caliper to stop squealing.

check the shims aren't touching the disk.

I remember while driving the old 110 v8 the forums say you should smooth off the brakepad edge to prevent squealing before fitting.

My defender brake pads have a lead manufactured on them, look on the right hand side of the pad in the picture.

So am I right in thinking that you ran your new discs with old pads? Or have I miss read that?

Hi, thanks for the replies. The pads do have a lead edge and I've fitted them in the correct way. I did run the new discs with the older pads as they still had some wear left on them and I'd been advised by a mate (he runs a motor racing team/is an engineer so trust his view) that best to run the discs in a bit and then replace pads. As I say there was still some wear left but wanted to replace with new before winter kicks in. Squeal is just at low speeds, and actually more when breaking on an incline rather than the flat. Not a train smash but annoying. Cheers again. Rikky 666

New discs must NEVER EVER EVER be run with old pads, regardless of how much life they have left. All you'll do is transfer all the wear ridges from the old discs, onto the new and overheat the new discs in the process.
If your mate runs a racing team, I'm glad I'm not a driver for him.
That practice is totally unacceptable for a track car but worse for a road car. I can't see how your life or someone else's is worth skimping on a £20 set of pads. You haven't filled in your location, so I hope you aren't near me.

I'll take that as a lesson learned then..........

Try a bit of copper grease on the ears and back of the pads. I have done tens of thousands of miles on Britpart discs and pads and never had a problem.

rikky666 · Oct 22, 2016

Thanks for that advice..........I'll use some copper grease and see how we go...........cheers
