Hello all, Thanks for having such an informative and active site. I picked up a 73 Maverick grabber for my 13 yr old son to restore and make his high school car here in Central TX. It has had some work done to it, but needs a bunch to make it nice and safe. I will have plenty of questions over the next couple of years, so thanks in advance for your help. The car has a warmed over 302--its .30 over, has '66 289 heads, a 268H cam, headers, 2.25" exhaust with flowmasters. It has '70 mustang front disc brakes with rear drums on the stock 8" rear. When I drove it home I noticed the brake pedal pressure needed was pretty hard and so I started looking upstream and found that someone has already put a wilwood dial adjustable proportioning valve in, but I'm not sure if the master cylinder is the right one for disc/drum. There is a lot of rust on the car and I am planning on replacing some of the mechanicals that are really rusted-the rotors and the master cylinder to start. We will have mucho body work to do down the road, but that can wait till we get it sorted out mechanically. Anyone with ideas about the right master cylinder replacement would be greatly appreciated. Thanks again and enjoying looking and reading about your cars. Bryon
from Northeast Pennsylvania Sounds like a nice project car I'm pretty sure that you could have ordered front disc brakes on a 73 Maverick - if so it should just be a stock replacement part
Welcome from Forney, near Dallas. Is this the car you bought? I have a lot of parts. Give a shout if you need anything. Rick
Thats It Yep thats the car. I got a few extra body parts to replace some of the rusted ones, and I did not get the Magnum 500 wheels. We have a good 2 + yrs to finish, and i've got race car stuff to do this winter, but along about March we will really dive into the Maverick.
from Florida. Re: Hard brake pedal .... even if it is a disc/drum MC, you will find that it takes a lot of leg to press that pedal unless it gets converted to power brakes. That is how mine is, I have a 1977 disc MC swapped into mine.. It stops great, but you have to lean hard on it. If the brake pedal rides a bit too high, or you find a spacer has been put between the MC and the firewall, then it probably does have the right disc brake MC, due to differences in the push rod. If the pedal height is correct and it doesn't look like it has been modified, then it is likely that you still have a drum MC. Some folks here report that theirs works fine with discs. That adjustable prop valve should be plumbed to the rear brakes, and is used to help keep them from locking up so easily with the better front brakes that have been added.
