LS1 Caliper Placement I'm currently converting to LS1 brakes. I would like opinions on caliper placement and why, I don't like the staggered positions of the stock placement of the rear calipers. Since there are many combinations, I'd rather just hear what those interested, or already have LS1s have done. |

Re: LS1 Caliper Placement so I can't clock the fronts, don't even no why I thought I could, but would have liked them outboard. Now the rear I can, so I'd still like some opinions on that. I am leaning to clocking them in board above center line (mirror image to fronts.) |
Re: LS1 Caliper Placement LS rear calipers are already in front of the axle. |

Re: LS1 Caliper Placement 1 Attachment(s) This is on my 89, left rear with 98-02 LS1 discs. I also have the pictures leading up to this during my swap if you'd like to see them. Attachment 382321 |

Re: LS1 Caliper Placement I have around 70 of the exact same images from my swap except I was converting from drum brakes so I had to cut/drill. |

Re: LS1 Caliper Placement Ok, while the fronts are cooking, rears are now a priority. I posted with a picture about axle bearings. You can see the huge difference in how the bearing is retained between a Posi and Open diff. The stock bracket is twice as thick as the '88 backing plate and would make it difficult to center the caliper carrier if not impossible. https://www.thirdgen.org/forums/tran...part-rear.html Any suggestions? buying a custom bracket it not an option, I need the parking brake. |
Re: LS1 Caliper Placement 2 Attachment(s) Ok for now I'm opting out on the P-Brake. I modified the 9-Bolt bearing retaining flange by rounding the corners as close as possible to the nut and circular. I machine an area center to the LS1 Bracket to the thickness of the 9-Bolt caliper plate and to a diameter wide enough to allow the bearing flange to recess to the proper depth. I also had to bore the mounting holes in the LS1 bracket to match the 9-Bolt bearing flange which has a larger bolt circle. I bought a 5 brake hose & hardware kit from Kore3, replaced the fittings on the inner hard lines to mate with the new hoses. The back of the LS1 bracket also needed to be widen to allow the 9-Bolt axle tube flange to sit flush without rounding the flange corners. When I tear it down to powder coat I'll install the P-Brake system. Attachment 229106 Attachment 229107 Back to the front |
