hi, i am going to do the rear brake conversion. what master cylinder should i use? i have disc brakes on the front already... and what studs do u use to hold the cylinder to the wall?
Same master cylinder you have now will do. Back when I did a 4 disc conversion on a 67 Stang, I used a 71 Ford Custom manual disc M/C.
I used the...stock drum/drum MC...on mine. being I had taller/bigger tires on the rear, I didn't use a...prop valve...
supposedly there is a residual pressure valve in the drum brake master cylinder that will cause excessive drag on disk brakes. i have never confirmed this and have seen plenty of rear disk brakes work fine with out changing the master cylinder. the other problem with using a drum master cylinder is that it has a small resivior that will empty pretty quickly as the pads wear out. joedirt posted a good part number for a disk disk master cylinder in his project build thread.
I use a '91 Ranger, with the fittings on the driver side of the mc. I also use a Wilwood distribution valve/prop valve/brake light module and it works great.
Mine is a '96+ Explorer/Ranger cylinder, without cruise. I used it because it came in a 4 disc application and it's available with a slightly larger (1") bore. I wouldn't recommend the large bore unless you have a booster, but if you do it's a nice upgrade. ...That being said, I also ran a Maverick disc/drum master cylinder for a long time and it worked fine. Only real difference I observed is the pedal feels better with the new one and the plastic reservoir doesn't leak around the top like the old one did.
I finally broke down and bought the Wilwood unit. I got tired of trying to make the stock one work. But it may have just been a bad master cylinder from the start. Works like a charm with the Wilwood though.
hello, can you tell me what Wilwood master cylinder fit in your maverick, because I want to change mine but I dont know what MC to buy, my maverick has disc/drums and manual brakes, thank you
Yes, I realize he revived an old thread, but this is still good information. dmboshkov, I am using Wilwood 260-8555-P The P just means it is polished and a bit more expensive.
