RE: [Chrysler300] 300 Disc Brake Conversion Update





Thanks Tony—how does it work? What do you think?

 

Used the F booster? Dual master?

Can wait till you do report, just wondering about results. One of the big mags put wildwood kit on a dart or something,  almost crashed late in test , as they are apparently subject to ‘knock back” ---what they called it --when rotors move on spindles or with axles on corner loading, the pucks get moved back and so many pucks and so much volume to fill then , that the master could not fill it on one stroke after driving hard at a track.  Big surprise, no brakes,  pedal to floor. Was working great before that . Lots of verbiage all around about that ---from all sides--- as you can imagine, but article left it unresolved, “working on it” . You experience any of that?  It gave me pause.

Thank you for sorting this out, great data,

 

John

Since my car has 15” wheels that accept 14” standard hubcaps we were able to use the larger rear kit with 12.9” rotors (140-10767-D). For 14” wheels there is a smaller kit with 11” rotors (140-11386-D).

 

For 1962 and earlier 8 3/4” rears, the bolt pattern of the backing plate must be redrilled to match. 1963 and later 8 3/4” rear flanges with flattened top fit the bolt pattern supplied.

 

Wilwood requires new green bearings to be pressed on to the rear axles. They supply clips to secure the bearings.

 

Both Wilwood rear kits have emergency brakes. If you still have the e-brake on the end of the tranny, you do not have to use the Wilwood set-up. If you want to upgrade, you can connect to them. Requires Lokar front universal kit with special order longer cable and Willwood rear e-brake cable kit.

The e-brake has brake linings that engage the inside of the rotor hat.

 

Front Wilwood kits require Wilwood front brake lines with banjo fittings.

 

Will be writing up a tech article with photos in the near future. Will post the link.
