Are you talking about the clip or the mounting bracket? I agree, that the clips should be spring steel, after a few test of mounting the aluminum clips on and off, the didn't retain the bend. I just didn't want to pay the $8 per clip from Toyota. I'll see if the car parts store near me has anything similar. If anything, the brackets will be temporary, I just want to slap the disc conversion ASAP. |

The Alu bracket will brake as well not just the clip, the brake hoses move back and fourth when pressurized under braking, this is going to stress fracture then brake off the mount right where its bent. It would need a triangle welded in to stop this or for it to be a properly cast unit designed to not bend. You can do the brake upgrade, just use the stock mount position for the trailing arm and stock brake brackets for now, Later on just move the brackets and change trailing arm position, changing the arms position only requires 10mins and a 17mm and extension and a jack. |

I painted my front calipers black, but I think I’ll paint them red along with the rear to make them look sportier. |

Its a minor upgrade for normal driving but if you live in the mountains or you drive aggressivly/take it to the track then this makes the car feels so much nicer. I had to do a hard stop yesterday on the motorway and she stopped on a dime, she will stop even better with the other suspension back in, just gotta bring myself to do another day out installing it all. |

I found some clippings of the stainless steel rails from work, they're 1/16 of an inch (about 1.6mm) thick, just what I'm looking for to make the brackets out of. I've made one bracket so far, while I'm on lunch break. |

Ok, I’ve made the brackets from steel. I drilled holes in the bottom where it’s going to mount so that the weld would hold better. Maybe a little over kill…
I’m hoping that I can convince my friend to come to my house and bring his welder, instead of me coming to his house. It’s forecasted that there’d be freezing rain where he lives this Saturday, but not where I live, although it’s still going to be cold, but Sunday weather will be better. I might weld on Saturday and install everything on Sunday. |

I would need to get the brakes certed again because if the mechanic notices its "modified" it gets marked as modified and I have to get the entire cars brakes certed...NOT EASY. Why arent you reusing the original brakets after cutting them off old position? |

It's wasn't that hard to make the brackets, and it would be easier to just cut off the original ones that I need to relocate with a hacksaw than grind off the welds, and I don't have a grinding wheel. Besides, I need to make two additional brackets to weld near the rear wheel hub for the hose that goes to the calipers, remember those don't exist on the drum brake version. My friend said he'd come here on Saturday, so it's game on this weekend!!! |

This project is making me lose sleep...
Last night, I was thinking too much about how or what I should be doing this weekend. I think I'll remove the axle frame from the car just to be safe, I don't any sparks near the gas tank, and I just filled up late last week. Not just that, also so I can get a good angle on the brackets I'm going to weld. I'm going to buy an angle grinder, I found one for $50 USD, I'll try to remove the existing bracket that needs to be relocated and see if I can reuse them, also clean off the other spots where the other brackets are going to be welded down. I'm debating if I should use the Yaris calipers or the Corolla calipers. It will depend on how the parking brake cable will be routed if the Corolla calipers are used. If you think about it, both the parking brake cable and brake line are on the top for the Corolla, which would make it easier to replace the brake pads, you just need to unbolt the bottom bolt and swing it up. |

I think Id go with the yaris set incase the caliper diameter is larger on the corolla calipers, No reason to mix and max brakes when you have the correct front and rear matching set which will give it the correct brake proportion. I always go with "keep it simple stupid" and its a no brainer to install the matching front and rear brakes. |

I thought of the same thing as you said, that's why I went ahead and bought the Yaris calipers, but I got to thinking how much convenient the Corolla's design is. I will show everyone what I mean how much easier it is to replace the brake pads when the Corolla calipers are used. Again, only if the route for the parking brake cables works out. We'll see this weekend. |

I got home early from work today and started some of the work, but quickly ran out of daylight. She’s dialed for the Corolla caliper, I’ll be testing how the cables will be routed tomorrow. E1AA266B-9024-40E5-B324-4B28FE187C8A.jpeg I hope it doesn’t snow tomorrow. Once I fit and test the parking cables then I’ll decide which calipers to use. I did get to put one of the parking cable on, I had to swap two brackets from the old one. |

Weight them, they have the same caliper diameter and rotor which means the braking force is equal so weigh them and use the lighter set, we already lost some performance with the disc brake swap already especially considering they are pretty huge for the size of the car, don't want to loose more for no real reason. Im going to get a light weight 15" space saver spare tire and remove the rear seats and rear seat belts to try to make up for the added weight. Plan to put a plyboard bed in cut to shape with a hatch for the spare tire because Ineed to fit a set of wheels in for autocrossing eventually.
Builds looking good so far anyway, get her done! Last edited by Compeer; 02-25-2023 at 08:54 PM. |

The parking brake cable routed just fine for the Corolla caliper, but I’m not decided yet to go with them. 7E10E337-71C6-4366-8734-2F88C8035BD9.jpeg I had some errands today, so I didn’t get to finish the install, but I did managed to remove the rear axle frame and install the parking brake cables. My friend didn’t show to weld the brackets, because the weather was too cold for him. I have no choice but to finish tomorrow. |

Alternative rear disc conversion complete!!!
She’s finally done! I went with the Yaris calipers after all. I’m going to redo where the relocated brackets are, I think I’ll put on the center bar of the H, but that won’t be happening any time soon. My friend is going on a trip, and he left today with his welder. I should have said yes when he asked if I want to borrow it for a bit.
The stopping force comparison would not be fair if I’m comparing to the drum brakes, because I also replaced the front brake pads and changed out the brake fluid. All I’m going to say is I’m very happy with the results. Here’s the before and after pics: |
