    Re: 1969 Mach 1 - Hard spot in brake pedal

    Hi guys,

    I replaced the MC over the past couple of days.  Man, I'm loving that flexible alloy brake line. Bled the brakes thoroughly and adjusted the proportioning  valve all the way in then backed it off a quarter turn.  The brakes were a lot better and improved substantially after they were heated up.  I tested hard braking from about 45 mph and the back brakes locked up pretty early, so I backed the adjuster knob out to 1.5 turns.  That seems to be a pretty good setting, but I'm sure it can be tweaked a bit more because the back starts to swing out to the driver's side once the back tires  lock up.  What are the differences in brake pad composition?  Would I get different braking (i.e. good initial braking, prior to heating up) with other pads?  (Before you ask, I can't recall what type I have on there now, since I replaced them early last year.)

    I didn't get a chance to contort myself under the dash to check out the brake pedal, but from memory the pivot point looks to be farther from the push-rod connecter than any of the short ones.

    Re: 1969 Mach 1 - Hard spot in brake pedal

    So I'm still not happy with the brakes.  It still takes too much foot pressure to bring the car to a stop.
    When I look at boosters, I come up with the following part numbers - and a WIDE variation in price.  Can anyone explain the difference?  They all state exact fit.
    54-76201 - $394.99
    54-73222 - $171.19
    54-73202 - $102.99

    Back when I originally bought the car, about 19 years ago, it had a booster with the band clamp.  The booster on it now does not have a clamp.  Of course the one with the clamp is the most expensive.  Given that the old booster had fluid in it from when the MC went bad, I suppose I'll replace the booster as recommended in this thread.  Is there a reason the prices are so different?  Rarity?

    Thanks,
    Hutch

    A midland booster has the band clamp.......Bendix booster does not.
    Hang on and MS will post his preference and why.....

    Thanks for the seguay. Josh.  The Bendix is better in my mind because it is a little smaller and does not have all the loose parts on the master cylinder connection.  They made it idiot proof so people do not take them apart and not get them together correctly.

    Prices vary widely because different companies sometimes have varying core charges and shipping charges.  You can almost bet that none of those places actually stock the booster.  If you order online, it will get drop shipped or, if out of stock, they will take a week to refund the money you gave them up front.

    I do stock the Bendix boosters, and I get the price I get because it comes with free 24-7 technical advice and I make sure you get the right booster for your application, and that the booster output shaft is correctly adjusted before I ship it.  I also have the formed steel plate that goes on the booster just like the factory used.  No one else has those plates, and buying a Bendix booster without the plate (none of the ones you listed come with it) is pretty much worthless.

    If you want one shipped right away, and have confidence that what you receive is what you need, and it has all the required parts, and is adjusted so you can bolt it on and forget it,  just email me and I will be happy to set you up with one.

    Money you enjoy wasting is NOT wasted money... unless your wife finds out.

    Thank you Steve!
    I appreciated the booster including new nuts and a push rod bushing.  I bolted it in without a problem in about 2 hours and now I have my old brakes back!  Ah, simple pleasures, like being able to stop when you want. :-) 

    I agree that this model seems simpler, without that aluminum/plastic spacer between the booster and master cylinder and with the hole in the front of the booster sealed off.  My problem in diagnosing the issue was that I was assuming I had a good booster after testing it on the bench with a vaccuum pump and it appeared to work.

    Thanks to all for the advice and feedback.  Now I'm off for a longer test ride.
