69mach1build 24 Report post Posted May 3, 2016 I'm finishing up my install of wilwood disc brakes all the way around on my fastback and I am currently planning on keeping the brakes manual. It is not a daily driver, wanted to get some feedback from anyone who has this setup and what the pros and cons are? 1 laurakk11 reacted to this Quote Share this post Link to post Share on other sites
moodster 55 Report post Posted May 3, 2016 I have manual drums right now that are in good working condition. I can tell you that in an emergency it takes a lot of leg strength to exert enough pressure on the pedal to stop quickly. I often wish I just had the correct brake booster because I don't drive the car hard enough that brake fade makes much of a difference. Anyways I would never have brakes without a booster again whether they were discs or drums. david Quote Share this post Link to post Share on other sites
RPM 1,238 Report post Posted May 3, 2016 I wish I did. Several guys here have them and will probably jump in. The important thing is to use the correct bore master cylinder. Which M-C does Wilwood recommend, and which M-C are you using? Quote Share this post Link to post Share on other sites

cavboy78 28 Report post Posted May 3, 2016 I have 4 wheel disc manual brakes on mine. x2 on what rpm said. They have a couple of different bore sizes and (if i remember correctly) the smaller is what you want with no booster. I have found that as long as you have a properly bled mc and lines, you stop just fine. Sure, it's more pedal effort, but if you stop all the same, I'm happy. The convenience would be nice if it's a daily driver, but i guess that's a matter of preference as well. Quote Share this post Link to post Share on other sites
Rsmach1 71 Report post Posted May 3, 2016 Usually 15/16 or 7/8 bore but depends on what calipers because of volume requirements. 1 RPM reacted to this Quote Share this post Link to post Share on other sites

moodster 55 Report post Posted May 3, 2016 I'm quite curious about all of this... what do you gain by not running a booster other then the expense of it? david Quote Share this post Link to post Share on other sites
69mach1build 24 Report post Posted May 3, 2016 I'm quite curious about all of this... what do you gain by not running a booster other then the expense of it? david It is going to be a very high cam motor. Weighing the costs/benefits before making my decision. Quote Share this post Link to post Share on other sites
fordguy69 24 Report post Posted May 3, 2016 I don't have discs on the rear, but I do have manual brakes with a Wilwood master cylinder that they recommended for the application. They work great. Make sure you use the proper manual pedal. The leverage point is very different for the manual brakes. If you use the power pedal, you will not like your brakes! Mustang Steve has the info on the pedals on his site. Quote Share this post Link to post Share on other sites

prayers1 153 Report post Posted May 4, 2016 I converted to 70 spindles w/ disc in front and 69 drums on back. I'm using what Chockostang sent me, a Manual MC from a Maverick which has the bigger bore (right now I can't remember what size) and a rear proportionate valve. The main reason I went manual was that my vacuum is 10* and I didn't want to lose anymore going to a booster. The car stops fine when I'm not on it, but racing and stopping is a different story and I do feel brake fade. I like my Magnum wheels and if I go rear disc, they wheels won't fit on the larger disc. If I should ever fine a nice set of 18" wheels then I would jump on rear disc and maybe a power booster. Quote Share this post Link to post Share on other sites
69mach1build 24 Report post Posted May 4, 2016 Those sure look nice! Shout out to a fellow bakersfieldian! These brake kits fit inside a 15 inch magnum 500 style wheel, for anyone interested. Quote Share this post Link to post Share on other sites
Rsmach1 71 Report post Posted May 4, 2016 I would probably go with the 15/16, but best to check with Wilwood and see what they recommend. Be sure to let us know what they say. Quote Share this post Link to post Share on other sites

Vicfreg 789 Report post Posted May 5, 2016 I have Front SSBC Discs with their Manual Master Cylinder and Equalizing Valve, and I have a 8.8 Inch Rear out of Ford Explorer in the rear with the stock disc brakes. Works great. Quote Share this post Link to post Share on other sites
craigm 25 Report post Posted May 5, 2016 Wildwood has pedal assemblies designed to be used without a booster, it has a higher ratio to help with pedal effort. That's what I plan to use on my build. Quote Share this post Link to post Share on other sites
