Guest zfan Posted August 30, 2001 Share Posted August 30, 2001 Im currently swapping toyota brakes up front in my 71 Z. The dust plates do not seem to fit do I need to trim the dust plates? They look like they need 1/4" off both sides. Am I wrong has anyone done the swap themselves? If so is there anything else to beware of or problems I may encounter?

fl327 Posted August 30, 2001 Share Posted August 30, 2001 youll definitely need to trim them, or remove them entirely... you might need a spacer to get the calipers to center on the rotor correctly, but i dont know, some people told me they had to use a spacers and shims and some tell me they bolt right on...i dont know.

Guest Drewz Posted August 30, 2001 Share Posted August 30, 2001 I trimmed my plates but if you are using the stock rotors for your year car spacers are not needed. Spend the money on good pads, I used Raybestos and found a good inprovement. Careful with the steel line as to not crimp it off when you do the swap. Good luck!!!

Guest scca Posted August 30, 2001 Share Posted August 30, 2001 you only need spacers for the vented rotor conversion.... although IMO the truck caliper upgrade is not any better than new stock Z calipers... with good metalmaster pads Quote Link to comment Share on other sites More sharing options...
BobsZTwins Posted August 30, 2001 Share Posted August 30, 2001 If you want to run the dust covers, you definitely need to trim them but they're not necessary. You do not need any adaptor for the caliper but if you want to run the '84 vented rotor you need to have a spacer fab'd to go between the hat and rotor. You will also need to trim the diameter of the rotor by 1/8". As to whether the Toyota calipers provide better performance than the stock with performance pads, it depends on what type of racing you plan to do. If it's just autocross or some street racing, stock's fine. If you plan to run hot laps on a track, you need the upgrade. When I ran 3-20 minute sessions at Willowsprings with stock calipers, I ran outta brakes by the start of the 3rd session! The next time, with the upgrade, I didn't even have any fade. But, even with an adjustable proportioning valve wide open, I still locked up the fronts before the rears. Still looking for a solution for that one!

Guest scca Posted August 30, 2001 Share Posted August 30, 2001 i would think if the fronts are locking the rears are not working up to their potential. go to a 15/16" master and see if the problem goes away. have you removed the factory inline prop valve???? and 84 300 rotors dont require trimming the OD to fit at all.... at least all the sets i've sold none have needed it...

blueovalz Posted August 30, 2001 Share Posted August 30, 2001 Locking up the fronts before the rears with a rear directed proportioning valve is unusual. Have you thought of removing or bypassing the valve altogether, or putting it up front? This peaks my curiousity as to the brake equipment at the rear and also the tire size difference between the front and rear. Quote Link to comment Share on other sites More sharing options...
