I wonder if StopTech is aware of this issue. This thread makes me second guess my desire to buy this kit.

I use a wrench or plier type tool and squeeze the pad against the caliper to depress the pistons.

I can only get the rear by hand the front is too hard for me so I use the above and then they slide out

I just use a lisle pad spreader, think the issue with the st-60s is bigger than that.

Worst case, you can take a screwdriver or thin pry bar and pry the pads out from the bottom of the caliper. You can use the rotor hat or studs (if you have them) as leverage on the front side. There's something to pry against in the back.

ST60s seem to be a minor PIA to get the pads in and out. The pads come out with a little effort in the ST40s. The key is to fully depress the pistons with spreader. I do apply some anti seize to the sides of the pads to make removal a little easier.

The pads should be snug as to avoid pad rattle...a really annoying clack, clack, clack sound at low speed. If they are too loose they'll rattle.

I was reading through the thread and was wondering:
Brembo pins and elastic metal leafs (or whatever they are called) are ingenious. Why doesn't everybody use this design? Patent or something? I doubt it since they were around for more than 20 years.

When installed the pads are always snug and are kept quiet. To take the pads out, all you need to do is tap out the pins. Then the pads just slide out effortlessly.

I always thought the stoptech bridge was the hottest ticket when it came to pad changes. No issues at all with mine.

In principle - it is. The bridge adds stiffness to the caliper while still offering the benefits of the open top for fast pad changes.

I called stoptech yesterday, and they are aware of the issue. It seems to be "batch" based. Some have the issue some don't. They offered to take my calipers, inspect them, and send them out to me no charge. I doubt I will go this route because I don't want my car sitting there with lines dangling. They declined a caliper swap. They also said I need to go through HP since they are the retailer.

I have a Lisle Pad spreader. I highly recommend it! It's less than 49 shipped on amazon, and it works GREAT. I tested it and it does clear the top side of th eStop tech calipers. So at least in principle the appeal of stoptech for fast pad changes is still there. You just need to make sure the abutment plates aren't going to give you trouble.

Sorry to bring an old thread back to life but I just had the exact same issue installing PFC '08 pads in my new set of Stoptech ST-40 front calipers. I had to tap each pad into its slot with a rubber mallet (more than a few taps). The brakes seem to be working fine but I was also nervous that this might cause a pad to get stuck in the caliper and not engage the rotor with as much force as it's supposed to. I am all for tight tolerances but this is ridiculous. I can't place all of the blame on Stoptech, though I wish they had designed these with a bit more clearance.

Interestingly 3/4 of the Stoptech street pads I had in came out just fine but one took quite a bit of effort to get out. I am now realizing that it might be a nightmare getting the PFC 08's back out since they are so tightly clamped into the pad slots. I guess I can always take the calipers off but that seems like a lot of effort on my part for a kit I purchased to make pad swaps easier!! <frustration!>

I guess once I get these out I will dremel the paint off each side of the backing plates and see if that helps.

Does anyone think this might pose a dangerous situation where the pads might get stuck on brake application? The pads are tighter than I would like but they are performing fine on the street in both light and hard brake applications.

BTW, I am heading to the track for the first time in this car next weekend so need to consider my options quickly, any advice is appreciated.

can you machine the rotors on the stop tech? My steering shakes every time i brake but the pads still have good amount of life on them

Brake shudder is related to deposits.

Based on how tight my pads were when I installed them I didn't think it was safe to leave them in like that, so I decided to pull them out this morning. I'm glad I did as they were jammed in there tight and ultimately I think they were unsafe.

I had to remove my calipers to get them out and even then had to hammer on them with a large rubber mallet to get them out after I had removed the calipers. I dremeled each side well past the paint and continued test fitting them until they slid back in with minimal rubbing on the sides. Everything is good now but I wanted to put this out there for those that have a similar issue.

I don't think it's safe to have pads installed so tightly, they should be able to wiggle around a bit so that when you hit that brake pedal there is no doubt the pistons will move them.

Super frustrated I had to do this but I think my setup is much safer now and I'm glad I put in the extra work to get this fixed correctly.

Best of luck to others with this same issue.
