RS29 Pad Rattle on OEM Calipers

[Clubber]

Hey everyone,

I searched here but couldn't find a definitive answer. I have been using Pagid RS29 pads,ss lines, srf on my OEM calipers and discs for almost a month on my CSL.

First there were no squeal or rattle but for the last week or so, I hear pad rattle while going over bumps and potholes. Mostly on vibration. I diagnosed it as pad rattle cuz it cuts when I brake.

My mechanic tried to widen up the brackets behind the pads but that only worked for a day or so and now the rattle is back.

I can live with the squealing but this rattle is a little too much. I read many people use these pads before moving on to full on BBK but no one seems to have the same problem. I was wondering if we did something wrong or if there is a solution ? Any input is appreciated.

Thanks,

Can

Thought pad rattle on these was from the rears only as they don't have a clip into the piston?

I am a bit surprised that after so many posts and threads people still ask why the Pagid RS29 pads on OEM calipers make noise.

Is that what it is ? Is there any solution ?

I mostly read about the squeling which I don't mind too much but I didn't come across any rattle complaint. Any solution ?

Easy solution. Buy AP Racing kit from Martin.
You will never regret it.

I will when my funds permit but until then I thought there could be some sort of solution without spending thousands :)

RS14 instead of RS29 on OEM brakes.
People read this and still put RS29.
With all due respect, you have been warned and you need to deal with the RS29 excessive noise now.

Alex will go on about RS14 vs RS29.

But that wont fix the pad rattle as neither have clips into the piston on the rear callipers.

So you need to some how attach the clip from the OE rear pads onto the Pagid rear pads and the rattle will stop.

That's very interesting to read, but I am 100% sure that the rear RS29 that I had for the OEM calipers had a clip.
Did something change in the last 4 years ?

Here is a photo from a guy that was selling a set in M3cutters

The rear has clip.
I would be really surprised if there no clip anymore.

Maybe I'm thinking E36, they definitely didn't have any clips and rattled a lot.

My RS29s don't rattle as far as I remember, but cant think of any reason other than not clipped in properly.

They do have a clip but my mech told me they were too short or too weak to tighten it in that caliper space. Even he stretched it a few times, they loosen up after a few hours of driving...

Then you have your answer.

Speak to Pagid to give you new ones.

try ceratec paste, its better than copper slip.

Mercedes ML and R class suffer with front pad rattle/clunk, regrease pads and it goes away, worth a try:thumbs:

They are already ceratec'd a few times. I noticed squealing happens when you keep driving in slow traffic. If you do a couple of high speed brakes, it cuts squealing for some time.

Coppaslip/ceratec etc will not stop the problem if they do not have the prongs fitted on the backing plates. For some reason I think Pagid did two types, weirdly one without the prongs.

To fix the problem...

Take an old set of pads, OEM/other and drill out the top of the stud holding the three legged prong to the pad.

Your Pagids should hopefully still have the stud on the backing plate. Fit the old prongs you just removed over the stud. Tack weld them in place.

This then allows your pads to locate into the piston like they should and then they wont rattle when off the brakes as are held still by the piston.


Alternatively, if new, send them back to wherever they came from and ask if they can be replaced. I bought a set of 2nd hand pads with good material left and had the same problem. Did the above and has been spot on.


Also, I have seen the posts on here from people who have had squeling that is so bad that they have had to spend £3K on a brake upgrade. Can see the benefit on track but is hardly a solution to noisy brakes. Have run RS29's on stock CSL brakes with no issues for 2 years as a daily driver and on track. As long as they get a good bit of heat now and again, the noise stays down. Was also speaking to another member on here about the same who made a good point as well - buff clean the disc properly if discs have had a different pad compound previously.

Rattle doesn't bother me, but coworkers always point it out when I arrive in the morning. Explaining that my car isn't actually broken is always a great way to start the day.

If I were keeping the car long term, I'd go with the AP solution. However, I don't intend to have the car more than another year.
