Hi All,
Looking to do the front disc brake conversion from helitool. I have a 53 B-3-126 PW.
For those that made the conversion:
-What master cylinder did you use?
-What proportioning valve did you use?
Here is a webite for tubing and other parts I have found. www.inlinetube.com
FAQ's
Do you have lines for me if I have converted my car to a dual master cylinder and disc brakes?
At Inline Tube, we make a variety of dual master disc brake conversions line sets for many popular cars and trucks. Line sets usually require our proportional valve and bracket in the system and then the lines are ready to bolt in for your conversion. Check this site or our catalog for the sets we offer.
Do I need a proportioning valve if I have converted to a dual master but have kept the drum brakes?
When converting to a dual master, no proportional valve is needed if the car is kept with all drum brakes. The system is simply separated to have independent front and back systems, so if one line should fail, the other half of the braking system will not be affected. You will need a distribution block that connects the second master cylinder line.
My car has a single master cylinder. Should I switch to a dual master?
If you are keeping the four wheel drum system, you do not need to convert to a dual master. The concern is that if you lose one line, all braking will go. The solution is stainless steel lines. They will never rust or deteriorate. When converting to a dual master, you will need a new master cylinder, a distribution block that will accept the second master cylinder line and new clips to hold the additional lines in place. When you are all done, you may affect the performance of the brakes with mismatched components, resulting in a stronger or weaker brake pedal. Brake safely with new lines from Inline Tube.
Do I need a dual master and proportioning valve if my car has been converted to disc brakes?
Yes. Disc and drum brakes require different pressures. Disc brakes require about 1000 lbs. of pressure and drum brakes use about 300 lbs. This is why the dual master requires a proportioning valve to control the pressure in the system. Whether the car is disc front or all wheel disc, a proportioning valve is required.
What size tube should I used for a custom job?
Typically, the smaller the tube, the more pressure it creates and the better the brake system will function. Disc brakes require about 1000 lbs. of pressure and the drums use about 300 lbs. Disc brake cars use 3/16” tubing and drum brake cars use ¼” tubing. If you are building a street rod that has front discs, the entire system is typically plumbed in 3/16” tube. All straight length tubing is available in 6' straight sections or up to 20' coiled.
What do you converts think??
