Getting ready to install LS1 rear brakes.

I have everything including the axle, but my question is regards to the rubber brake line.

After installing all hardware, will the LS1 rubber brake lines bolt right up and be the correct length?

to be honest....i think lt1 rears are better than ls1 rears...no point to the swap

The LS1 brakes are clearly superior brake when you look at the big picture, although its debatable if its worth the time and money to convert. I got them and they are going on and you definitely the first I have heard who thinks the LT1's are the better brake.

That being said I need to hear from people that have done this and what to expect when it comes to the brake lines. Can we please stick to the topic at hand.

When I converted mine I used the LS1 hardlines and rubber lines to the calipers. If you don't have the LS1 hardlines it shouldn't be hard to bend the LT1 ones to make them fit. I think the LT1 or the LS1 rubber lines will work once the hardline is bent.

I used the original LT1 rubber line from the brake line on the body to the axle.

Okay, I got my e-brake cable brackets out and saw the provision for the brake line. It was all very clear what to do at this point ans the lines with a little persuasion are not hooked up just like factory.

It is really amazing how dissimilar the LS1 and LT1 rear calipers really are. The LT1 has a smaller bore and piston and is terribly overly complex in design.
The LS1 caliper has the bigger bore and piston and is so simple in design it is really laughable.

The LS1 caliper is very much superior and I m willing to bet it is more of an upgrade than the nay sayers will admit.

Aptly said, like anyone that spent the money on them.

I always thought they were about the same size. If so, I would not expect a noticeable change in performance.

I did this conversion as well, the LS1 rear rotors are not much bigger in diameter, but are quite a bit thicker and have alot bigger cooling fins in addition to the caliper having a larger piston and a much more simple design.

Although I gotta admit, I wouldn't have bothered with this upgrade if it had not been so cheap in my situation...

I took all my parts from a donor rear axle out of a wrecked '01 V6 f-body. The whole conversion cost me a total of about $100, only because I decided to replace the e-brake cables and buy a new center soft line

I will be able to sell my complete LT1 brakes for around $150 to someone with drums once they are cleaned up and painted.
When it all comes out in the wash I will have the full rear upgrade for around $110 with new rotors which I needed anyway.

The other benefit will be the much better parking brake. My LT1 e-brake barely held even when properly adjusted. The damn thing is so tempormental. I have driven an LS1 and the improvement is 3X plust the brakes are much easier to service.

I found a 98+ donor car in the junkyard. I will be sure to get the axles because they are different. Longer or shorter, I don’t know? I will also get the brake lines, both soft & hard. But this car is a four channel ABS because the sensors are at the wheels. Mine is a ’94 six speed so it has the three channel ABS. How much does the 4/3 channel complicate things? Can I just simply keep the single ABS connector in the middle of my rear end and ignore the sensors at the wheel for the ABS? Or should I just wait for a three channel ABS 98+ F-body to show up at the junkyard? Just FYI, I am getting the front brakes too. Thanks, Shimaze
