After a long or particularly hard drive, I get this weird grinding noise under braking. It only does this under light – medium brake pedal pressure at all speeds below 30mph. Above that I can’t hear it. It sounds like its coming from the front left (passenger side for RHD vehicles)
So far I have replaced discs, pads, swapped the front springs/shocks with another used pair, replaced wheel bearing on the left, flushed and bled the brake fluid.
I did the work myself but then took it to an inspection place but couldn’t recreate the sound there, so I recorded it and thought I’d share it here too.
I’ve had the wheels off so many times now to do a visual inspection and can’t see anything wrong!
Any ideas?

That’s interesting stuff… I’ve had no problem using Ceratec on a few other cars. (not to mention the other 3 calipers).
It seems to be the go-to in the UK… the average mechanic seems to leave the slide pins alone during a brake job. (as witnessed after inspecting my friend’s car who had his pads and discs replaced at an independent garage). Other than that, a few people have said they use red rubber grease for caliper pins.
I’m not convinced the issue is Ceratec. My new caliper was sliding freely and I haven’t removed the pins to see what grease is being used in that, but it is definitely not seized.
I’ve emailed them to find out!
If they say it is not suitable then I will be having some strong words with the parts store!
Sadly, many “It’s not my car” mechanics in the USA neglect to properly lubricate sliding caliper pins, too.
Not a recent phenomenon, either.
That poor attitude had already infiltrated the workplace at least a quarter century ago.
I am interested in what Pagid says about their product.
It could be totally suitable for the pins–and I hope that it is– but asking them is certainly the best way to find out.
