Strange Engineering Master Cylinder
Can anyone recommend what # Strange master cylinder, for me, to run? I cant remember if drum(4 corners) require a bigger bore or smaller bore, than disc fronts...
I have '68 Firebird, with 4 wheel drum... tired of the Orielly's junk thats on there now... Since i put it on, its never felt right...I know there is a Chrysler part, that compares to the Strange, but not sure what it is... THanks!

Re: Strange Engineering Master Cylinder
With the 4 wheel drum brakes, use the stock 7/.8 master. Best holding and stopping power with that. In my opinion.

Re: Strange Engineering Master Cylinder
7/8 bore? The problem im having, is, pedal is hard with no real feel, and it wont hold in burnout box, again... i thought i had that problem fixed, last year. Whole brake system is new... I have a strange on the '62, but dont know what model it is...it works great... Napa or Carquest might have a NEW cylinder...rebuilt ones , are junk...

Re: Strange Engineering Master Cylinder
That does sound like it may be an oversize master. Look on a site like rockauto.com where they have pictures of the part and give the bore size. As I recall a 93 Lebaron is a 7/8" of the sterotypical Mopar style dual cap master and a 95 Dakota is 15/16".

Re: Strange Engineering Master Cylinder
Have somone pump the petal while you bleed the lines. It sounds like you may have an obstruction in a line. You should get a high pressure squirt at each wheel if everything is correct. A stock master should work fine with drum brakes. Have you replaced all the stock lines? For drum brakes 7/8's master should be the ticket. If you changed from power to manuel brakes then your problem is the petal ratio. Power brakes have a much lower petal ratio and you must redrill the petal and increase the ration for manuel brakes. It may also require relocating the master for a straight shot from the petal thru the rod to the master.

Re: Strange Engineering Master Cylinder
Richard's probably got the right answer.
Most power brake pedals have a hole that gives about a 4 to1 ratio. If thats the case, just calculate the distance to get about 6 to1 and drill a new hole in the pedal. Definatly 7/8" -15/16" for drum / drum system

Re: Strange Engineering Master Cylinder
Richard, my car is factory manual brakes... all system is new...i didnt bother to check the piston size, when i installed the Master Cyl, about 1 1/2 yrs ago... ive since changed line locks, thinking that was the problem, but i believe its just the wrong master cyl. Or, its just a piece of junk. We used the Chrysler part, on my brother's 10.00 car, and it worked perfect. I just couldnt remember what car it came off of... All you have to do , is , notch the holes out , a bit, make a new pushrod, and you are in business....Ive bled brakes several times... doesnt help... BTW, the car drives like a Caddy, with the Global west stuff, adjustable Baer tie rods, and moroso springs... lifts straight, now. It used to twist on launch. 1.485 60fts , with bracket engine and 4.11 gears, bias slicks, 2400 footbrake...
