I had the OEM brake pads replaced a few months ago with Porterfields. These brakes squeak terribly. At as bad as the OEM. Any thoughts on how to fix the problem? I was thinking they might be glazed since I don’t really really put a lot of pressure on them. Mainly city driving. I have got some speed up and then get them close to locking and it might help a very little. Any ideas?

 

If the porterfields are track pads, squealing comes with the territory, especially if you're just using the car on the streets or GT and not tracking it. If you would go with a ceramic pad, those do exceptionally well on a street car and they shouldn't be noisy. I have ceramics on my street DB11, notorious for squealing and mine doesn't

Besides a good street pad, I use this product and have been for a long time now on every brake job I do. In fact, just did brakes on a Toyota Saturday and used this product. You would have to disassemble everything to just try this stuff, but if it were me, I'd change pads and use this stuff.

 

I got the porterfield S(street) pads, put the antisqueak on the back, then tried to do a proper bedding procedure.

Mine squeaked a bit at slow speeds, but they seemed to have totally bedded in now and are good to go.

If you didn't get the street versions of the pads, you may be SOL and need to swap them out.

 

I installed the street version of the Porterfield pads on our 2007 V8V about 4-5 years ago. Rotors had been cleaned when the new pads were installed and I bedded them in. Had some squealing at low speeds.
Took the pads off and applied some disc brake quiet (can't recall what brand) and bedded them in again.
It helped but still had some squealing for about 200 miles. After that it has all but disappeared.

 

Thanks for the info. I have the street pads on my car but I have a feeling the shop that installed them did not put any anti squeak on them. I do mainly drive around town at lower speed but I notice if I use the brakes at higher speeds the squeak goes away. I was wondering if Imhave some glazing because of the mainly city driving I do. I will redo the bedding procedure to see if that might help.

 

I just replaced rear - poterfield pads and brembo rotors used red antisqueal paste and on street pads no break in required... just normal driving for about 100 miles with nothing aggressive...no noise very little dust

 

I had Portefield street pads for a year on my Vantage, (mainly wanted to get rid of dust) It was squeaking from day one, I've tried paste & hard braking.... nothing stopped the squeaks. Got rid of them, installed DFC 5000 series ceramic pads, no squeak at all.

 

Funny I have been running Portefield pads for 10 years on my Vantage and never once they squeal, guess I am one of the lucky ones

 

I'm a member of a Vantage group on FB and many have switched to Portefield pads to eliminate brake squeaking with great success. It's have a '23 Vantage with only ~5K miles but have not experienced any brake squeak. I suspect this is due to the low miles

 

Mine don’t squeal. Porterfield make a few different types of pads. I suspect the squeal folk don’t have the same pads as us quiet folk.

 

I had Porterfield's on my 2007, and haven't yet done the pads on the 2006 yet. Not to be pedantic but...the bedding in procedure for Porterfield pads is counter intuitive when compared to other performance pads. The first set I put on, I cooked bedding them in using the traditional method....and then I looked up their recommendations and realized what had happened to create the truly terrible squealing. The replacements were bedded properly and I used the orange goop on the back of the pads, no more issues.

 

I went with Dynamic Friction Company low metallic low dust pad, no squeaks, very low dust, and same stopping feel. Pads on all 4 corners with E pads was right around 200, very affordable

 

Switch your pads to Dynamic Friction. They perform great and your squeal will be gone. They're the only frictions I use on all my vehicles.
