I wanted to post this up for everyone to know about.... I've been looking at all of the various rear disc conversions for my '73 FJ, and I just didn't like the idea of using Monte Carlo calipers (or El Dorado to keep a parking brake). Well, I have another option that y'all might be interested in.... I installed a rear disc conversion on my 2006 Tundra from SOS Performance. They offer the typical "big brake kits", but I wanted something that I could get parts for at the local Auto Zone, if needed. They also offer a kit that uses 2005 Sequoia rear discs, with the internal drum parking brake / "top hat style" rotors. Here's a link..... REAR DISC CONVERSION Backing Plate Kit / TR.PS2.TU6.BPK fits 2000-2006 TUNDRA I contacted Tom Watts, the owner of SOS, about doing a similar kit for my FJ. After a few Facetime calls to look over the rear axle, and me taking some measurements for him, he's decided to put together a kit. The plan is to have backing plates that bolt on in place of the drum backing plates, and will include the necessary park brake cables, and balance bar to actuate it from either the dash mounted lever ('58-'79), or the floor mounted lever ('79-'84). The Sequoia rear discs do not need to be machined out, like the Chevy rotors, and with the exception of the backing plates, and actuating cables, everything will be late model Toyota parts, that can be purchased at any parts store. I'm working out the details for cable routing, length, etc..., and will be sending him my drum backing plates to measure for precise dimensions, but it shouldn't be too long before a kit would be ready for sale. Tom ran some numbers, and it's looking like a street price of $425-ish, shipping included. The buyer would need to either buy new Sequoia calipers, rotors, and park brake parts, or pull them off a salvage yard rig, like I did for my Tundra. I'll post updates and pictures once I get the prototype parts to fit up, but wanted to get this out there, so folks would know it was coming.
