Brake squeal

Hi all,

I'm having a strange squeal for a while now on my left front brake.

When I drive in the city at +- 30 km/h and slightly turn the steering wheel. Like very very slightly, I get an intermittent squeal without touching the brake pedal. It's usually worse when I've driven the car for a few km already and used the brakes a few times. I've had this problem last year already and reinstalled the calipers and pads a few times. I've putten on copper grease on the back of the pads, and then the squeelling would stop for a week or three, and then it starts again. It doesn't get worse or anything.

I'm pretty sure the discs are straight. I didn't clock them but I never feel vibrations when braking. I checked the disc tolerances which are within spec. I changed all the rubber seals inside the caliper and that didn't help. I'm guessing the return hole or the brake line itself? But does the return hole work for both front calipers or only one caliper?

Advice would be greatly appreciated.

Thanks in advance.

Probably the pads. May as well get good replacements and fit (many have anti squeal shims).

Bosch pads come with the anti squeal backing, had them about a year (9000 miles) and they have silently served me well so far so i can recommend them. They are far better than the unipart squealer pads they replaced

Have you checked that wheel bearing for slight play, that could cause your brakes to squeal especially when turning the steering wheel, because the disc could now be out of vertical and rubbing on the pads.

might sound stupid but have you checked the metal plate behind the disc , some times they can become bent and catch some thing causing them to squeel , also check to make sure it is secure and not rusted threw or rusted at the mounting bolts.

I haven't checked the metal plate yet.. I'll check it out this week if I can.

I've checked the wheel bearings for play but I don't feel any play. I've had the problem for a year by now, had the wheel of several times and passed the "Belgian MOT" without problems. I'm about to go again in two weeks. About the pads, want to mention that they only squeal when not pushing the brake pedal.

Thanks for the tips I'll check them all out.
