General Brake Squeak

[Mike1alike]

Internet very slow today, picture does not upload but will try again later...

It's ok. We'll wait for it. Don't stress about it.

Brake service and adjustment along with a mere lick of lub on the back plate pads resulted in an extremely good handbrake, just like over 5 years ago.

Where exactly did you put lub there?

hi admin, you can remove the picture taking the most "digital space" if you wish, to save space if needed.

Punto rear brakes back plate. No thing more pleasueable than si tting in the garden in the warm sun, with a pannad to my left using the most versatile hammer in my collection given to me 56 years ago, chipping off corrosion, ready to place in the Tesco double strength lemon squash bath, which removes all corrosion and paint, leaving the steel alone.

The back plate pads that need the slightest smear of lubricant for quiet efficient rear brakes can be seen close to the large hole for the wheel cylinder, and the bottom fulcrum/shoe stop.

The centre pad and hole are for the shoe steady pin and slide on spring clip.

The shoe ends in contact with the wheel cylinder piston move the most, with the auto adjusters *reaction bar* sliding in the open ended slots.

Out of adjustment auto adjuster means shoes move more, with thier inner contact ( steel on steel ) area rubbing on the back plate pad.

No lub and corrosion on the pad can and does cause a squeek.

This squeek will happen using foot and handbrake.

I like to give brakes a pre summer, and pre winter service.

The auto adjusters fail to work when the unit is jammed due to brake duet.

Adam's squeek may well he due to lack of lub on these pads.

How is the hand brake Adam ?

How is the *compensating bar" by the hand brake cable adjuster, cocked over ?

Yes I had a rear brake clean up regarding this last year and the issue stopped up until about a month ago. They clean and adjusted the rear brakes.

Surely this doesn't need to be done every year.

Will try and test the sound again a little bit later on.

Technically it does, in that the brakes should be ‘inspected’ at each annual service. However, in practice, so long as they all work ok and pass the standard for an MoT, it can probably be left to alternate years, given your relatively low annual mileage and the fact that the Pands seems to be very ‘gentle’ on their rear brakes. Often these sort of squeaks happen in a dry springtime after winter salt causes a bit of corrosion - but will go away by themselves with regular use.

Nice giving the back plate a chemical clean. I use an electric screwdriver with a wire brush head, its versatile but a lot i can't get to.

Yes it does too

Handbrakes are prone to all sorts of noises, i'd not worry about it unless you think the brakes are faulty.

You have seen the *before* picture, the after picture to follow when it's ready for painting.

You may be surprised by the result.

Those pads need a lick of lube, else they will squeek.

Be sure to post the result.

I think Adams brake shoes need a little grease.

I won't be surprised. I know the citric acid is the best cleaner!

I tried the powdered citric acid mixted will water but was not as good as the Tesco double strength lemon squosh.....

Sone years ago a nazi plane was lifted from the English channel and taken to raf museum, metals treated with lemon juice ( citric acid ) which removed corroeion etc. But left the good metal alone.

Used to his lemon juice on a rusty metal box lid with hammerite remains, lifted all paint remains and all corrosion leaving, once rinsed and quicky dried, a perfect surface ready for paint.
