Squeaking brakes on V8V

[Montezooma]

Just recently my brakes have started to squeak/squeal horribly. As I'm sure you can imagine I'd rather not pull up at traffic lights to a high pitch squeal drowning out that wonderful engine!

Basically, in the first few miles the car tends to be fine, not making any noises. As the journey goes on the brakes start to squeal - it does tend to be the last few metres as you come to a halt, i.e. you're pressing the brakes, but not particularly fiercely.

I've searched and it does seem this is a specific issue for V8Vs, but the last topic I found didn't give a clear answer about what should be done - so, any suggestions? (including cost would be great)


In case you it helps to know: the car is kept in an underground car park day-to-day, I generally only use it at weekends, and because it's been so miserable haven't been driving it as much as I'd like recently. It's due its 4yr service in April.

Thanks in advance

Its a common problem not just on the Aston
Usually easily sorted by a good clean and careful use of copper grease.
Unless your "handy" a job for the dealer or some one like Rick @ DMS.

I applied a little Coppaslip to the rear of my pads, made a vast improvement. 97p all fixed!

try re bedding them in properly too - if you dont brake hard for a while they seem to get worse

whenever they start to make a noise, just follow the procedure on Pagid website

I used to do this with other cars that I upgraded to same Pagids that are standard on the Vantage

[blackice1]

In a word you are not driving it harder enough ;-)

Mine used to do it, they got fixed and then 2 months later it comes back again; humph.

And yes in my case it's because I don't brake hard enough and therefore the pads don't get used much.

2nd car arrives in a few weeks though and then the Aston won't be used in so much traffic.

Was at a service clinic recentley with a guy from the factory, he said that a lot of town driving can make it happen more than on a car thats regularly hammered down the lanes.

I didn't need telling twice...

Can absolutely confirm that.

I'd always spell it out that the copper grease goes on the back of the pads not on the face! Seen a few threads over the years where people have slapped it all over their brake disks!!

It seems that recommendations form PAGID are in complete conflict with the recommedation in the owners manual of minimal hard braking in the first 400 miles of use. Which is correct.

fair comment
Back of pads and both sides of shims, I'm going to chamfer the edge of the wear material on my pads slightly as well. Then rebed them as per the Pagid web site

[millsjq]

Does anyone have a photo of how much of the brake pad to chamfer and should it be the leading edges only? My car (just purchased) had the brakes pad changed and shim kit installed 400 miles ago, car has 5K miles total as the orginal owner complained of brake squeaking. The car has been total quite until yesterday and now get worse every mile. Has anyone actually had sucess by the high speed braking beding in? Since the dealer is 2+ hours away it would take less time for me to pull the pads champer them and add additional cooper grease. Is there any type that has worked better than others?

Pagid ...user manual is generic owners manual stuff likely been copied and pasted from the first manual ever written LOL (probably something to do with some legalise anti getting sued crap from US)

[MrOrange]

I'd adhere to the Pagid process which, off the top of my head, is 5 medium braking (which is a actually quite a big prod on the pedal) from 70 to 30 with half a mile inbetween. The 3 big stops from 70 to 10 with light braking inbetween, same half a mile gap to let the brakes cool.

Followed some of the tips on here and now no squeaky brakes

were these the "do some heavy braking" tips?

and thanks all for the input, shall be doing the same shortly.

Yep. I built up slowly, mainly for my own confidence. First a couple of 50 mph stops, then a drive around to cool the brakes, then one a around 70 and finally one a around 90.
