A high pitched squealing has developed on my 2005 Honda EP3 at front driver side wheel. Suspected brake issue although it stops when applying brakes and continues when released again. The problem does not begin until warmed up or 5 minutes into drive and also only happens at low speeds.
Link below for my problem, thanks.

Have you taken the wheel off yet to have a look?? If so does everything look OK? How much 'meat' left on the pads? Is there anything stuck between the disc/backing plate/caliper etc etc?

No idea what an ep3 is.

But sounds like pad sticking or caliper slides. Pedal pressure forces it past and stops the noise, only to stck again when released.

Strip and investigate. I would be expecting slightly uneven pad wear. Either across a single pad, or inner and outer pads different thickness.

Does it have the pads with the metal strips that rub on the disc to alert you when the pads need replacing? If so it could be that.

The bit of metal on the left of the top pad.



Edited to add pic.

Don't talk yourself out of it, that is exactly what the issue is, the only thing that changes when you apply the brakes is the application of the brakes so that is 100% the issue.

Could be a sticky slider, a non-releasing pad, a pad shim, a pad not seated correctly etc. etc.

As was stated above you need to get your wheel off & start looking around.

I would assume a wear sensor would also squeal when applying the brakes so my money would be on the slide pins. Should be an easy and cheap fix especially if the front but I would rotate each wheel to be sure you've got the right one.

It could be corrosion in the slide pin hole which can push the rubber grommet against the slide pin and causing it to stick, or someone previously using copper grease to lube the slide pins which can react with the rubber grommet and cause it to expand.

I would remove the caliper, slide pins and rubber grommet then buff/sand the hole (dremel is great for this) and ideally put a new rubber grommet in. If you decide to lube the slide pins (some people don't think it's necessary) then use a silicone based grease like Mintex. Also buff any corrosion or crap off the slide pin and reassemble.

Personally I would do all your brakes just for good maintenance purposes but you may need a rewind tool for the rears. Cheap to buy from Halfords. Mind to remove the cap from your brake fluid reservoir.

I had exactly the same problem and this fixed it completely.
