Hello All smile

As you know may/may not know, picked up the vantage from stratstones just over 1 week ago. After a while, the brakes seem to screech quite loudly (not all the time). Probably only done 400 miles since i've bought it.

I'm wondering if the pads are worn or could it be something else? Any way of checking? I'm thinking whether they are worn although surely they would of checked them before putting the car on sale.

Thanks in advance

The vantage uses quite hard pads which are prone to glazing which in turn causes the screech.

Two things to try - when it does it, look at the car in front of you & shake your head - that will convince some of the pedestrians about that the noise is coming from someone else.

To try to de-glaze take the car up to 70 - 80 and when the conditions allow, brake really hard down to about 10 mph - do that twice & the shine should be off the pads. One further word of advice - after you've done this, the discs will be quite hot, so drive normally for a little bit to let them cool down

the OE pads are Pagid and need bedding properly from time to time

only other solution is to change pad compound

Blimey, so as well as starting up the car 3 times (for clutch learn), which makes people think I can't start the car properly... I also have to brake hard 3 times to stop the d*mn thing squealing, which makes people think I can't drive it properly!

Just kidding, thanks for the tip. The squeal was annoying me yesterday while stuck in traffic. 3 hours to cover a 10 mile journey should give an indication of how much time I was stuck in traffic and putting up with the squealing brakes!

Stop driving like a girl and brake later and harder!

As said above, they will glaze if used lightly, especially in traffic.

I had this on my Vanquish a month or so ago. There is no end of crap that people will tell you, some of which helps but none of which seems to work... Other than getting different pads. Some say copper slip the back of the pad etc. Braking heavily ain't a solution as I stamp on my pads and am a late breaker.. For most it seems to be the last 15 to 20mph down to zero and it's pretty ambarassing in an aston

HOWEVER, the other week, after fitting factory pads with Aston at their shop, which screeched from braking less than 15 mph down... I chamfered he leading edge of the pad. Suffice to say... It worked instantly. They haven't squeaked since. One of the racing guys from the auto Rome suggested it and it worked. So there you go. Hope it works for you mate. And, it worked in the porker too!

And... Aston Martin bed in my pads when they fitted them,... According to the schedule and speed they set. Still didn't help.. Until I chamfered the leading edge just a tad.... Hasn't squeaked since and that was a while back. Prob actually more like a couple of months since I fitted them actually.

So they will start Squeaking again when you have worn the chamfered off, or have you chamfered them all the way to the back plate.

The Pagid link referenced above recommends chamfering the edges at 45 degrees as well as specifying the bedding in procedure.

I keep getting this on the rears on mine (had it on both)
Dealers struggling to solve it.
Just been told by an AM dealer it is because of the copper rivets used to attach the friction material on to the metal backing laughnono
I'll have a fettle over the winter I think

Touchwood, I haven't had any experience of squealing brakes on my car....I'm not sure why this is, but one thing I do usually when I clean the car, is crank up the compressor in my garage, and give the brakes a good high pressure blow jobsmile

Just a trigger type blow gun, aimed at the calipers through the spokes on the wheel.... Not sure if this is why I don't get any squealing, but there's a surprising amount of dust that gets blown out..... Enough for me to wear a breathing mask and some safety specs....

when DMS fitted my last set, they did chamfer the pads, put coppaslip on the back, and use the anti squeal shims ...then I did the bed in thing, and all was fine

...until I dont use the car often enough, or just do motorway journeys for a few weeks

its just a quirk of this pad compound + disc combination, I had similar when I ran Pagid RS42 with AP discs on my old Elise

Yep
In fairness Wilmslow did dort on my old car
JCT tried on the S but my recent 4.5k mile jaunt with out cleaning borught it back.
As Bogie says probably a quirk of the pads and light use.

I'm surprised at how common this issue is!
You would think they'd sort this "quirk" out as it's quite embarrassing given how loud it screeches ears

As I've stated before: swap the stock pads out for a set of Porterfield RS4. No squeal, no need for bedding-in, and substantially less dust.
