Pumping Brakes

[Bruce69Camaro]

I installed a manual disc brake kit on my Camaro. I'm using a Strange M/C, adjustable proportioning valve, Strange rear drum brakes, 3/16 steel lines and also #3 braid steel lines going to the calipers and wheel cylinders.

As far as I know I got all the air out of the system.

The other day driving it, I had to pump the brake pedal at least three times to get a solid feel.

Is that about a normal amount to pump the brakes?

Thanks

Sounds like you still have air in the system.

I didn't know Strange made drum brakes?

[Bruce69Camaro]

They make a 11" drum kit for the nine inch ford using the big and "New or Torino" big bearings.

I'll double check and make sure I got all the air out.

Thanks

How big is the piston in your master cylinder ?

[Bruce69Camaro]

That's getting a little personal isn't it Harry...

1.032" which is good for a system with front disc's and rear drums according to S&W Racecars.

My strange brakes did the same thing. It took forever to get all the air out.

I had to pump them up real good and then crack open the line AT the MASTER cylinder. After i did that a couple times they WERE GOOD TO GO!!

Thanks for the tip Adam, I'll keep that in mind when I bleed them.

Do you have a line lock?

[Bruce69Camaro]

Yes, got line lock.

Did u bleed the line that goes into the Line Lock?

Why would you need to bleed the system from this point? A line lock is simply an open valve until power is applied,air and fluid will just flow through it.

Well this weekend, my wife helped me bleed my brake system and found some air in the rear lines.

Now on the second pump, it's solid.

Now, have a question for guys with big tires, how do you know when you need to make an adjustment to the proportioning valve?

thanks

well i would say adjust it till you can lock up the front brakes then back off till they won't lock up and that should mean your using all your wheels to stop now and you are just boreder line locking up the front brakes then you should be about 20% rear and 80% front braking

Did you plumb it to the front or rear?

[Bruce69Camaro]
