Brake Rotor and Caliper interchange

BlackRoseRacing · Post by **BlackRoseRacing** » Fri Jan 11, 2008 7:10 am

Front rotors:
01+ JR body - p#4879138AA - 11.11" diamter, .905" thick, 1.265" tall
03+ PT/SRT turbo - p#5273141AA - 11.025" diameter, 1.102" thick, 1.55" tall
02+ PT Non-Turbo - p#4509994AA - 11.025" diameter, .905" thick, 1.54" tall
00+ Neon - p#5273038AA - 10.115" diameter, .866" thick, 1.5" tall

Rear rotors:
03+ PT/SRT turbo - 5085652AA - 10.63" diameter, .472" thick, 2.09" tall
All 95+ Neon/PT non-turbo/95+ JA/JR body - 5085651AA - 10.63" diameter, .355" thick, 2.09" tall

Apparently the 01+ JR body Stratus,Sebring share the same rear rotors as the neon, its always possible that its front rotors might also fit the neon if you had the PT/SRT style front knuckles. Also note, the turbo cars have a thicker rear rotor and they are the same diameter as the non turbo just thicker on the mating surface. So an SRT rear brake setup is not an upgrade.

PS - all dimensions were taken from NAPA's website interchange, the part numbers were looked up through Chrysler

Good reference to have! The rear rotors could be considered an upgrade if there is alot of extreme braking required or heavy loads in the trunk, as the extra thickness may held with potential warping, if that is even a problem. But then they (should) weigh more too. So It's prolly a wash.

Any ideas if the JR bodies use the same rear caliper? If so, with some slight modifications ( to the dust sheild and such) you could probeley get a JR body BBK for the rear to work (such as these)

BlackRoseRacing · Post by **BlackRoseRacing** » Fri Jan 11, 2008 4:37 pm

I compared the front JR rotors to the neon and it looks like they might not work since the neon rotors are deeper than the JR rotors, so much for that thought

That would move the caliper out almost 1/4". Even if the knuckle would accomidate that, it may cause wheel clearance issues.

so you're tellin me, that DCX put LARGER diameter rotors on the back, and smaller ones on the front for the 4wheel disc neons???

kinda stupid if you ask me...

But overall diameter doesn't directly correlate to pad clamping area, does it (also called swept area I think)? Remember the rear discs also have the drum style parking brake inside it. Therefore I could imagine a large overall diameter rotor and center hat section, but a small band of rotor that is being clamped on by the pad.

Update: 4-26-08
After spending the past week trying to get replacement rear calipers I found a little bit of information...........
1990-2006 Chrysler FWD Non-Turbo rear calipers are 95% interchangeable
Chrysler FWD PT/Turbo FWD cars rear calipers have a larger piston than the non-turbo and the piston and outer boot are not interchangeable. The caliper sliders bolts and boots are also the same one's used in about 98% of Chrysler FWD vehicles. Which means the slider kit for my wife's 94 Caravan is the same slider kit my 2002 R/T uses at all 4 corners.
With this said, those of you wondering if the SRT rear calipers will fit the R/T rear brakes, I'm 99% sure they are a direct bolt on upgrade to the stock calipers.

Rear calipers are NOT interchangeable 198x-2006

Somewhere around ~2000, the thread pattern for both the banjo feed line and the bleed valve were changes from standard to metric.

The metric banjo bolt, while very close is not the same diameter as the old standard bolt was, so technically the hole in the end of the brake line is a slightly different diameter to match the proper banjo bolt for that model year.

Depending on the quality of the seal with your copper crush washers you MAY be able to run a standard banjo bolt caliper on flex lines designed for the newer metric banjo bolt, but I wouldn't recommend it. The metric banjo bolt won't fit through the hole in a line designed for the standard thread bolt.

Note: parts counters, interchange books have no idea of the above and will try to hand say the caliper is the same for all years.

I ended up having to purchase a brand new rear caliper from Mopar for my 01 R/T and even the Mopar caliper came from the factory with a standard thread pattern bleed valve hand tight installed. Hand tight of course because the standard bleed valve was slightly smaller than the metric threaded hole it was in.

To clarify:

87-1999:

2 different rear calipers: 32mm piston and 36mm piston, both utilize standard thread banjo and bleed screws

2000+

2 different rear calipers: 32mm and 36mm pistons, both utilize metric banjo and bleed screws. (R/T's got 32mm, SRT - 36)

As for the front rotors, the P body are almost identical to the PL body. The P body rotors may be like 1/16" more diameter, but I don't think it would cause any clearance issues with the caliper.
This was side by side comparision of aftermarket "P" VS oem "PL", so tolerances may have been a factor.

P body = Sundance/Shadow
PL body = Neons, of course

hmm silly banjo bolt, is the brake hose end the same where it connects to the steel tube n the car?

Whoa ..... GREAT info !!

Although the 2nd gen rotors are 2mm thicker than 1st gen rotors, I've still seen warped rotors occur.... Extra meat wouldn't hurt.

Thank you for discovering this & posting this, Occasional.

being that this says interchange, would i be able to swap out my brakes on an 00. with srt4 front brakes/calipers?

i have drums in the back, could i swap those out with srt4 rear brakes.

if i jacked this thread. someone please p/m me.

Info: PT Cruiser GT and SRT-4 front brakes = 99% the same, including part numbers.
they fit perfect!

what may the 1% be?
SRT brakes are red - PT grey...

sooo just wondering, would i be able to put srt calipers and rotors on my sxt wthout changing the knuckle.??

Danteneon · Post by **Danteneon** » Mon Apr 11, 2011 8:32 am

No. You need to change the knuckles as well.

furyman67 · Post by **furyman67** » Sat Jun 11, 2011 11:25 am

So could I use the knuckles from a PT GT on my 2000 ES if I want the bigger front brakes

Danteneon · Post by **Danteneon** » Sat Jun 11, 2011 11:49 am

Yes. The PT GT knuckles will work as well.

Since this has been bumped...

OK this reminds me: The "P" rotors are thicker overall when new. This may keep the loaded caliper assy from fitting over the rotor, unless some pad material is removed. Turning the rotor would be counter productive. This would still be a feasible "upgrade" for non street use, or if you don't care about a little less pad life.

Do 2000 + Calipers and rotors fit 1995-99 neons ?

dawm · Post by **dawm** » Wed Sep 05, 2012 2:46 pm

FYI, 1g rear calipers will work on a 2g. You just have to drill the brake line banjo hole slightly larger and use the 1g banjo bolt (I have done this on my 2002, since i had 1g rears under warranty at autozone

)

i just thought i'd throw this out there as well for those looking at doing the big brake upgrade.

you could also opt for these rotors. for a 1993 chrysler lebaron GTC.

front: 11.02" diameter, 1.1" thickness. 1.55" height. 5x100 bolt pattern.
http://www.napaonline.com/Catalog/Catal ... 0302877967

rear: 10.63" diameter, 0.47" thickness, 2.09" height, 5x100 pattern.
http://www.napaonline.com/Catalog/Catal ... 0302877968

i used these front rotors on a K based vehicle, along with grand caravan calipers and brackets a few years back. sort of wishing that i'd kept the hardware. either way, they are just a slight bit thicker rotors than the SRT spec'd rotors, and many parts stores carry them still oddly.

blueneo03 · Post by **blueneo03** » Thu Feb 28, 2013 10:49 am

so i was looking but i just wanted clarification..... an N/A PT cruiser rear disc will swap to a 2gn correct? and is it like with the 1gn->2gn where you dont need the spindle and all, just the hardware? and how about e-brake lines?

fargo59 · Post by **fargo59** » Mon Mar 04, 2013 10:38 pm

i think i just discovered more to this that i think is totally cool. i'll be sure to fill you in once im 100% sure i'm right. lets just say i found another source for "turbo car" rear brake components.

i REALLY hope this works. lol.

does anybody know what master cylinders interchange? I know that disk/drum and disk/disk and 11"/disk have different bores but i cant find a 11"/disk master cylinder that does NOT have abs because i upgraded to pt front and disk rear and i have my factory disk/drum so my rear brakes drag and its not the correct size bore i think this would be a good addition to the info with these brake differences
