THE BANDIT-Z

I just purchased this brake line kit from summit(Earls 28190). I lifted my car from the rear (both sides) to check if the new lines fit,and what do I find out. My passenger line (left rear) looks about the same lenth as the stock(rubber) one,the ceter rear also looks the same,but the driver side"right rear" (short one) does not fit? Why because there is a braided line running from the "center rear" all the way to the driver rear caliper. The supposedly "right rear" line from earls kit is to short to fit, also I havent checked if the fronts fit (hope they do). So has anyone run into this problem, I dont know if i should keep it being that the driver rear already has a braided line(if the fronts fit also)? Please some one post something, anything, whatever.

I think you have the wrong "4 wheel disc" brake lines set. What year is your car and is it a 4 wheel disc car? I know Spohn lists 3 different sets for the 1LE cars and disc brake cars.

If it's the wrong set, see if he'll trade you for the right ones.

My car is a 1985 Iroc-Z 305 T.P.I/700R4 I still havent checked the front ones (this weekend) but the passenger rear one looks the same, the driver rear doesnt . It is a braided (stock line) all the way from caliper to the "divider T". My car is 4 wheel disc brake, but I dont know if the rear axle is original?

Apeiron

I didn't think the factory used any braided lines.

TRAXION

It's the wrong set. 28A190 is for 1LE front disk brakes and the aluminum PBR caliper rear disk brakes. An '85 doesn't have that configuration. You want a set that fits single piston iron front calipers and single piston iron rear calipers. BTW - the Part Number you want is 28A520.

Hey traxion so your saying to return this kit(28a190) and get 28a520? Thats the correct kit for my car? What about the braided (stock i think) line that runs from the driver rear caliper to the T line, will this kit (28a520) replace it also? Does summit have this kit, or do I have to get it from another place?

I dont know of ANY braided stock lines...Mine used a METAL line to the TEE.... In 1985 I dont believe there was a DOT approved way to run that much braided line to a brake setup...

THE BANDIT-Z

Hey Kenwood have you installed a Earls brake line kit to your car? How did you do on that braided or metal line on the driver rear line,is there a kit that also replaces it or just the other three and the T line ?

I just got some braided lines from summit for a non 1LE

It so happens that I also have an 85 IROC with 4 wheel disks and also installed the Earls brake lines. Someone has changed a line under your car. The line going to the LH rear disk is supposed to be a hard line, not a flex line. The "T" block in the rear has a flex line on it but not the driver side caliper.

oh the good old earls brake line kits

even after getting mine swapped with spohn i still havent put them on yet, still waiting untill i need to change fluid, pads, and rotors.

THE BANDIT-Z

"WTFAJITA" I cant find that part # on summit, only the ones I ordered(wich now im returning-1LE)? Where else can I get that kit I really need it .

Morley

Welp, I looked at my kit box and it was 28A190, same kit you have. I put it on my '85 IROC (4 wheel disk), all hoses reached where they were supposed to. I ended up not needing the real short line from the kit though.

TRAXION

PN28A300 is for 4-wheel discs where you have Iron front calipers and aluminum PBR rear calipers. This is most often for cars 1989 and after.

PN28A520 is for 4-wheel discs where you have Iron front calipers and iron rear calipers. This is most often for cars pre-1989.

PN28A190 is for 4-wheel discs where you have aluminum PBR front calipers (1LE) and aluminum PBR rear calipers. This is for 1LEs.

28A190 will not fit front iron calipers. You want proof? Here it is with pictures courtesy of me ...

TRAXION

That's exactly what I am saying.

1) PN28A520 is the kit made for your car (iron front calipers and iron rear calipers)
2) I've never seen a braided stock line on thirdgen. Somebody did that before you bought the car.
3) Summit has this kit.

Here is what I think will happen if you buy the 28A520. The front brake lines will fit fine. The passenger rear will fit fine. IF the kit contains a fifth line that runs into the 'T' on the rear axle (feed from Master Cylinder) then that line will fit fine. It is the driver's side rear braided line that will not fit because you do NOT have a stock setup. Somebody replaced your rear driver's side rubber hose AND steel line with a single braided hose. My advice would be to EITHER find a stock replacement steel line for the driver's side rear and then use the Earl's braided line in the kit OR to just leave that side alone and continue to use that replacement braided line that is on there.

Tim

Morley

Well, they sure fit on my iron calipers, front and rear.

TRAXION

What I have posted is true and others have run into the same problem (Momar, vwdave, etc.) when trying to use the 28A190 on stock front iron calipers ... plus my pictures clearly show it so there is no argument that there is a fitment problem.

Tim

THE BANDIT-Z

Hey traxion your pictures show the same dilema (problem) that im having. Also I cant seem to find the part # you gave me on summit online? Do you have to order it by phone only? The driver rear hard line(stock) wont be replaced with the kit because all the kits come with a real short line for that side? Man im confused

SteveSpohn

There are four Earl's kits for the thirdgen, you can see all of them here:


http://www.spohn.net/category.cfm?categoryid=1095


You can NOT use the 28A190 with iron caliper rear disc brakes. That kit is specific to 1LE cars, meaning 1LE front brakes and PBR aluminum caliper rear disc brakes.

Thank u all I already found them on summit ( EAR-28A520 Brake Line Kit, Hyperfirm, Chevrolet Camaro 85-88, 4 Wheel Disc exc Hi Perf $95.95). So this is the kit for my car traxion? I just asked a friend that knows more about brakes than I do and he said the stock driver rear line is "metal" line from the "T" to the driver side rear caliper. So I wont be needing that short earls line rite?

Morley

My instllation clearly shows that there was no problem, the lines fit perfectly.
What happens is that (as stated in Earl's instructions) there were several plumbing "options" GM used throughout those years and even within some model years.
I am the original owner of this car, the calipers were never changed, there was no 1LE option for the 85 Z28/IROC (I ordered mine option by option), it came with iron calipers at all 4 corners. I ordered the Earl's 28A190 Hyper-Firm brake line kit and installed it on my car myself, no fitment problems what-so-ever.
There is no argument with rolling, running proof that those lines will fit an 85 Z with 4 wheel (iron) disks.

TRAXION

Morley,

This has nothing to do with a 'plumbing option'. The Earl's hose ends from the 28A190 kit PHYSICALLY do not fit the recess in the stock iron calipers. If they fit yours then GREAT! But, you are the only one on this site that has NOT had the problem when trying to use the 28A190 with stock front iron calipers. Everyone else has. So, either your calipers are different, the front Earl's hose ends you got were different, or you actually used a different PN without your knowledge. The only reason that I am stating this is because I don't want someone in the future to do a search and buy the 28A190 thinking that it will fit because you said that it does. In every other case it HAS NOT fit. Dude - that's why Earl's offers a kit specifically for front iron calipers (28A520 for iron rear calipers or 28A300 for PBR aluminum rear calipers). Even Earl's knows there is a difference.

Tim

TRAXION

As long as you have front iron calipers and rear iron calipers then that is the kit for your car. Your friend is correct. It should be a metal line from the "T" to the caliper. So, if you keep that braided line that is currently on your car then you won't need to use that driver's rear line from the Earl's kit.

Tim

Morley

Nope, nope & nope. I still have the box they came in, 28A190. The calipers being different is one of the plumbing "options", GM used different parts through model years.
"Dude", just because you or someone else couldn't get it to work doesn't mean it won't

TRAXION

... and like I said before -- YOU are the only one who did get it to work without any modifications. Earl's makes a specific PN for front iron calipers and 28A190 is not it.

Bandit, Someone at sometime mickey-moused your rear brake line. You should not ever have a soft line (not braided nor rubber) that is that long. It should be a hard line. When you plumb a hydraulic brake system, it should have a few sections of braided line as possible on any car or any system. Hard lines do not flex and loose pressure- soft lines do (even braided- but not as much as rubber)- get the factory hard line back on there.
