Squealing Brakes

Driving around in a car that is 27 years old, there are always little quirks and noises that come with the deal. Occasionally they get to the point where they need sorting. Generally I move it up the list based on how dangerous it sounds v's how much time I have to fix it.

Recently though the brakes have started to make a horrendous squealing noise, which although isn't dangerous, is so bad on the ears that it needs sorting asap. Below is a short video highlighting the problem.

After a quick read around the subject, it seems that fixing the noise is fairly straight forward.  As the noise is caused by the vibration of the pad against the brake piston, anything that reduces or even stops that vibration will solve the problem.

The easiest way for me to achieve this, is to take the brake pads out and paste a good dollop of copper grease behind them. So starting on the drivers side, I jacked the car up and removed the wheel to reveal the brake caliper.

Wheel off.

Pulling the pins out of the caliper with a pair of pliers, the brake pads were extracted and examined. These particular pads were only fitted last July when I overhauled the drivetrain so they are still in fairly good condition.

Pins out

Although at the time of fitting, I did slap some copper grease on the back of the pads, it looks to have worn away where the piston makes contact.
Pads out

Using a brush, I applied a new layer of copper grease to the back of the pads and popped them back in the caliper.

Copper Grease...
on the pads...

Once both pads were done and the caliper was properly re-assembled, this side was done.

I did the same to the other side of the car also.
T'other side.

Once both road wheels were back on, I took the car for a test drive and, bliss!! The car was free from it's demonic possessions once more! Well at least until the copper grease wares off again anyway!!

Total time faffing about on this was about 25 minutes. I will see how long it lasts this time and if it's disappointingly short, I will have to see if I can find a more permanent solution.
