Porsche 996 Brembo BBK Conversion Install

[maupineda]

I’m hoping someone has a fix for this issue. I just installed my 996 brembo brakes and my fronts squeal like a stuck pig. I just removed, lubed and reinstalled everything and it still squeals. Any suggestions would be greatly appreciated. Thanks

I had this issue on the rears with Textar (Porsche) brake pads. I solved it by using the dampening pad of a set of ceramic brembo brake pads I had laying around. These Brembo brake pads have a backing pad made of metal but “wrap” with a rubber layer, and since they just glue and attach with metal tabs, they could be transferred to my Textars and they are now completely silent

if you look up brembo ceramic brake pads, the red color piece is what I call the dampening “pad”.

i hated the ceramic brembos, low bite, less brake power, and yes, no dust, but I want brakes that perform more than dust, just wash the car more often.

My front pads are the brembos and they squeal like a stuck pig right before you come to a stop at slow speed when hot. I too don’t care about dust since I usually detail it once a week, but the squeal is irritating. Is there a pad that squeals less?

My problem was as you described but at the rear. What I told you is how I fixed it. I did not even use any grease.

my fronts are BMW Performance calipers with Textar pads also and they dont squeal at all. So different setup.

what Brembo pads you are using? Not all pads are equal. Are you using the ceramic ones? But by the sound of it they are metallic, and without some insulation they will squeal. My front textar brake pads also have a plate with rubber so I am sure that is why the dont squeal.

Does anyone have the part number for the ceramic pads (ie quietest) front pads? Sounds like swapping pads would do the trick. Most e46 m3 race cars I have heard are quieter than my current set up!! Thanks for all the suggestions!!

Are these the correct pads?

Are these being used and pads still sqeal?

Those Textar pads look like they have the rubber shims on the back, plus they've got the weights up top.

Do you know if they happen to be the correct pads?

I use the following and they have no dust and no noise:

Front Pads:
https://www.fcpeuro.com/products/por...akebono-eur917

Rear Pads:

Those rear pads give full sweep but the inside pad requires some trimming if you used the ECS brackets.

Did you use shims on the front pads? Thanks

I did not use the Porsche shims. Those pads have a metal backing plate so I left the shims off and added some brake grease where the piston hits the backing plate.

Just go thru the full install and i had to get the CM ecs front brackets machined. It's a bad product. Stick with rally road for the brackets both front and back. I bought a kit from someone so I ended up getting the Creation motorsport brackets in the front and they don't even come with shims. Anyways I'm happy it's all done and working now !
here are some pics during install

Hi OP, sorry to hijack the thread but since I am in the process of doing this conversion, I thought I could add a few more pictures feel free to move them to the main page.

today I spend most of the day trialling the callipers (rear) to modify the dust shields, I wanted to do this before I paint the callipers so I don't risk scratching them during the mockup and proceed to cut the shields to accommodate the Porsche callipers.

I am using rally road brackets

So the first step was of course to remove the wheel, calliper, and rotor, nothing out of this world here; I also was very lucky and my rotor screws came out pretty easily

Below you can see the share I followed for the upper part of the dust shield. at this point, I had cut just enough to bolt the upper section.



Next, the lower part, I did this to avoid cutting too much and follow the pattern of the mounted calliper, as you can see it was not much what needed to be cut just to seat the bracket, but you do need to cut off some more for the calliper to clear.



After cutting the shield I was able to mount the calliper



So far so good, but then I also checked how centred was the calliper in relationship to the rotor, and I found that is 3.2mm too car inboard. the bracket kit comes with 4 washers but they are just 0.8mm thick, so for the calliper to be centered I would need to use the 4 washers on one calliper, so I need to get some stainless washers from home depot.

See how the supporting pin of the outboard pad is contacting the rotor



Here you can see how much clearance is on the inboard side (that gap is 3.2 - 3.3mm), I measured it with feeler gauges. in this very picture, you can see where the bracket seats to the knuckle, there it is where the washers need to be placed, ideally 1.6mm thick to put it in the middle.



I will post a photo of the other side so you see the final product of the cut, I did use my Dremel smooth out the cuts and since I don't drive on the rain or winter I am skipping paining it for now as I would hate if I spray other bits in the process, plus you don't see it at all. bellow

Digging up this old thread since I'm putting these brakes on my car pretty soon. I think the reason your calipers were not centered is because they appear to be the wrong caliper. They look like the 986 part number calipers not the 996 ones. Are you able to confirm the part number cast into the caliper?

Almost done with my rear 996 install but EURO 737 pads not seating properly on inboard side. The EURO737 pads extend out the additional 5mm to avoid the rust ring that forms over time on the 328mm rotors. The culprit? The Creation Motorsport BR0020 brackets! It looks like the Creation Motorsport brackets don't have a "groove" like the Rallyoad brackets - see pic below - so the "taller" EURO737 pads can't clear. I don't know why Turner (and ECS) continue carrying and selling this junk. Turner is always my go to but this is disappointing.

I guess I can Dremel the groove in but it that advisable? Or bring it to a machine shop to machine the groove in? Or just take the $170 loss on the CM brackets (been sitting on install for more than the 3 month return period) and get the Rallyroad brackets for peace of mind? I know, these are brakes we are talking here so the answer should be obvious to me.

What would you do?

azmirm5 Pretty sure this was mentioned in the 996 brake conversion thread by Tbonem3

If it were me I'd have a go machining them, but it does seem the rallyroad is worth the extra cost. They're lighter, better hardware, and obviously fit the proper pad.
