lt1/ls1
I was gonna to possibly drop by a junkyard that has a few camaros and i was curious... What did 4th gens come with... both LS1 and LT1? If so how can i tell the difference? If i find one with LS1 id take the parts but i dont wanna assume they're LS1 and it ends up that they arent..... The other thing is, what exactly do i need to get parts wise? Just backing plates and callipers/rotors? Forgot to mention its for the rear.

Re: lt1/ls1
rear axle? lt1 brakes have the calipers on opposite sides of the axle, one side is on the front, other side in on the back side of the rotor. follow? ls1 discs are on the front of the rotor. ASAIK, the lt1 discs have a spring and weight parking brake, whereas the ls1 has an internal drum parking brake inside the rotor. Much cleaner setup.
grab everything you can. Rotors, if they are good, calipers, abutments, all bolts, backing plates, need to pull the axles to get them off, parking brake cables, the entire parking brake assemlby. you want the cable that attaches to the e-brake handle in the car and goes intot he tunnel, there is a puller plate thing in the tunnel you want as well as the cables to the rear. Or you have to buy custom cables from ebmiller. Grab the flex lines for the calipers if they look good, might want to get new ones anyway. and grab the e-brake cable brackets that are bolted on with the LCS's that hold the flex lines and the parking brake cables.

Re: lt1/ls1
Get the rear end out of the 2000, it'll have the 12" rotors and all the good stuff. I actually got a rear end out of a 2000 to work e-brake wise with the 2000s factory e-brake cables and balancer off the handle, so where everyone else has to spend a fortune on cables, i got mine free, and readily available. Besides better brakes, the rear end is newer, probably less miles, and possibly better gear ratio than what you have. I have '88 Formula wheels on mine, and they fit perfectly in the wheel wells with air shocks. Without air shocks they want to rub the 245/50 tires i got.

Re: lt1/ls1
Not saying your wrong, but is it at all possible for the LT1 calipers to be mounted on the back... on both sides? Stopped by the JY to check out what they had and i looked at a 97, both were mounted on back... The 2000 on the other hand looked semi descent, asked what they want... He said that calipers,all bolts, backing plates, e-brake cable would be like $85, n that itd probably be more worth it just to get the whole rear end, which would be around $180.
if you have the choice, defiantly get the ls1 brakes, they are better and cleaner looking

Since the rear calipers are slightly different i dont see being able to put "CAMARO" on them, not enough room.... Thats why i ask if fronts can interchange with rear..... or would some customizing/fab be needed?

The Delco-Moraine calipers, 82-88, are on opposing sides. The 89-97 PBRs are on the back side.

Re: lt1/ls1
So what exactly is the vibration dampener? Not asking what it does but part wise (what it looks like)? Is it part of the caliper bracket/abutment or whatever the correct name is, or part of the caliper itself? Id like the rotors same size all around. I dont really need multi-piston calipers on the rear, i'd just like the caliper to have the room to paint 'CAMARO" on them, like the pic of the blue caliper i posted.

BTW, many members simply discard the piece as unnecessary.

It's a rubber donut-looking piece bolted to the e-brake assembly.

Re: lt1/ls1
The 89-92 PBR version wasn't equipped with the dampener, and I've experienced no problems without it, so why the dampener was incorporated in the first place is a mystery to me. I'd chuck it if it caused difficulties.

Re: lt1/ls1
Ls1s have PBR calipers on them too dont they, cuz my ls1 brakes say PBR on the caliper. I know they are ls1 brakes cuz they are monted in the front, have ls1 style ebrake and the rear end had the TCS ring in the rear end.

Re: lt1/ls1
Need 2 questions answered por favor....
The first... As far as the LS1 backing plates goes, how often if at all do they need to be rebuilt? Also does anybody know if they have rebuild kits for the plates? (Couldn't find any kits)
The second... As far as braking goes would it be fine if I was to use a set of front LS1 calipers on the rear as well? I'm more so asking if it would be ideal to use the basic two piston front and one piston rear or my way. (Basically what I am asking, would having two piston calipers all the way around the car bring up any issues braking wise?)
That's all for now, thanks.

Re: lt1/ls1
Not on the rears! Don't know about fronts, but I'd imagine not.
Also NOTE: Most 3rd gen factory spares WILL NOT fit over the LS1 brakes either - even if you have 16" wheels from factory, chances are the spare will not fit over the LS1 brakes as the factory still usually used a standard 15" donut - so anyone doing the LS1 brake swap or swapping in a LS1 rear end needs to get a larger donut! I have no idea about the earlier 'spare with a can of air' setups.

Re: lt1/ls1
Couple of questions.....
1) Whats the difference between say getting a used oem PBR caliper vs a reman one like from the auto parts stores?
2) Anyone have any recent experience with Big Brake upgrade .com?
3) Why is it not required to use axle retainer/plate when installing LS1's on a Moser 9", does the backing plate act as a retainer?
4) Any one have a write up or know where i can get instructions for installing the LS1's on the 9"... (write-ups ive seen are vague)(9" is spec'd for ls1's from moser).

1. remanned ones are rebuilt, used are used, is that hard to get?
2. never dealt with them, heard good and bad
3. yes the backing plate acts ars the retainer
4. caliper goes on the front, install the plate on the axle before you press on the bearings. insert axle, bolt to axle flange with t-bolts, should be supplied with rear. pretty straight forward. If you remove the brake backing plates from a car at the junkyard or where ever, just look at how they are attached. they attach the same way on the 9" with the exception that you have to install them on the axles and press a bearing on.

Re: lt1/ls1
Was wondering if someone can tell me the correct name for this part... (PIC FOR REFERENCE)...
The little cylinder that engages the brake shoe... What would that be called... wheel cylinder? Now for the pic of the backside that shows the lever, is that part of the cylinder or are those 2 different parts? N what would that be called? Thanks.

Re: lt1/ls1
Is it alright to give a quick sandblast to the caliper bore, or is that a no no? I figure i could go back and use a real soft wire wheel (real soft) and just polish the bore back to the original shiny surface without removing material.. Would like to hear opinions...Thanks.
