New Brake Pads?

[brzskids]

So I am looking into purchasing new street brakes. Currently I have my eyes on the ferodo ds2500 brake pads. I have 2 questions:

1. Should I purchase both the front and rear brake pads?
2. Do these brakes work fine on the stock rotors/calipers?

Sorry I'm a big noob with braking system. Just want to make sure my selection is good to go. Also any tips to prevent squeal besides brake grease? I heard these brakes can be loud if not bedded properly

The pads will work just fine. I would not replace just pads though; get new blank rotors as well. You will have no issues

Welcome.

Well, to answer your first question, depends how far gone your rear brake are. If they are ready for replacing then go on ahead.
Or, if you got the money to spend, get it. There is really no wrong answer to that question.

Yes they work fine on stock rotors.

Yes you should bead them properly. Yes they will still be noisy. That's the nature of the beast when it comes to high performance brakes.

Now, that being said if all of your driving is 98% on streets, and 2% is on a race track, then these pads are not meant for you. You might want a notch lower or just deal with the added noise. It's up to you.

1. imho yes, they are likely very different in terms of how they grip the rotors vs. the old pads and may cause a bit of funnyness depending on which pads you replace.
2. Measure the disc thickness, if it is above the minimum it won't be a problem to keep the old rotors, the minimum thickness is in the owners manual. No reason to change rotor 'style' if you decide to get new ones.

When I put them in I performed ~6 hard braking maneuvers from ~60 mph down to 20-30 in quick succession to get everything nice and hot, do not engage ABS, then cruise for 10-15 minutes without stopping if possible to allow them to cool and not create any uneven transfer layers.

My DS2500 are not very noisy, a light squeal at low speeds, zero effort on my part to rebed or keep them quiet. They are overkill for street but are perfectly fine imho, I wouldn't take them to the track, they're not track pads.

I've heard these brake pads are fairly quiet? Can anyone confirm?

I used them year around including winter (on stock brakes. experience may differ if on BBK). Not completely quiet, if unbedded they may squeal here & there at light braking, but not stupid-loud, so in my book noise-wise they are acceptable for street. They did dust more.
bzrskids: they will work on stock brakes, IF you will buy them in shapes/sizes meant for stock brakes (as pads of same compound are made for many different brakes out there). For twins stock brakes IIRC DS2500 part numbers were FCP1639H front, FCP4187H rears.

What are you trying to accomplish with pads? If it’s just street driving, even spirited, stock or similar type, pic your brand is fine. If you are feeling some brake fade during spirited runs then you could upgrade to a better compound and brake fluid with high dry and wet boiling pt. I am on stock pads and rotors and brake fluid at 51k. Many highway miles, but plenty of spirited miles with real no issues, just saying.

Yessir those were the exact brakes I had my eyes on. Looks like I'll be going through with the purchase today!

My brakes are starting to feel squishy. I'm assuming they are like 10-30% life remaining. Need some nice brakes LOL!

[ls1ac]

They are a fine pad for street and lite track duty. If you want to do it like a pro, you can lightly burnish the rotors before installing them to remove surface buildup of previous pads. Then hard bed them as they like higher temperature's.

the manual states you're supposed to change the brake fluid every 30k miles. a squishy pedal could also be water-logged fluid if you're well over the mileage.

Yeah im ordering some stainless steel brake lines + ate brake fluid right now.

Just 1 question: My ds2500 brake pads came in but no shims+clips included. Is it fine if I just reuse the ones already on the car?

Yes. Just clean them up a bit.

[churchx]

brzskids: yes, they come that way. You don't need "backing plate shim" with those. But you need those shims/clips where "ears" of pads move in caliper (if not reusing/reinstalling those, then pads will rattle around).
Also, if old pads were worn down a lot, you may need to press in pistons a bit, and check after changing pad (and pressing in piston) on each corner brake fluid level. Thicker pad -> deeper pushed pistons for pad to fit in -> fluid level will rise. After 2nd-3rd-4th pad there is possibility for fluid to overflow (if it had been topped to normal level with old, thinner pads), if you don't remove excess fluid with eg. syringe.
