Master Cly Install Help
 

This mite come as a surprise to a lot of people but I am working on my race car and it is sat and I am looking for info. I have a Lamb master cly to install on my car. The front has what I believe to be 9/16 by 20 thread the rear is 1/2 by 20, without going looking on some old cars to get the line nuts that work does anybody offer new pieces that will work without having to stack different adaptors on it? I will be using 1/4 line for the rear [ still using the stock rear brakes] and 3/16 for the front with Lamb fronts. Also what line goes to the front and rear. Cars brakes worked ok back in the day with stock master with check valve removed for the fronts. Thanks for now Tom

Tom, Roger Lamb did my entire brake system and furnished straight fittings for his master cylinder. During assembly I decided that banjo fittings would be more suitable and was able to purchase those from Jerry Bickel but I'm certain that either type fittings would be available from most full service chassis shops. Roger Lamb's instructions were to connect the front brakes to the outlet nearest the mounting flange (rear) and the rear brakes to the forward most fitting. Although I do have to say that I have seen several high-end cars with the brake connections in the opposite configuration (front-to-front/rear-to-rear). In support of Lamb, I can truly say that his products have been literally plug-and-play; not a single problem or adjustment required.

I don't know the answer to your install with 1/4" line on the rear, my lines are 3/16 both front and rear; that might make a call to Lamb worthwhile. Hope this helps.

We end up going to Pik a Part for 9/16 x 20. Can not find it elsewhere.
we run 3/16 everywhere. Front of cylinder goes to back or we can not
stop worth a darn. I would like to find the fitting elsewhere if anyone know.

Tom, it's likely a 9/16"X18. Dorman has what you need...here's a link to their catalog page:

If you can't find them locally, let me know and I'll drop some in the mail to 'ya. -Al

Today I used a thread gauge to it and they are both 20 pitch with one being 1/2 rear the other is 9/16 front. I am looking for flare nuts to go onto the lines themselves no AN. As far as the 1/4 to the rear for the drum brakes that was the way it was since I have had the car [1983]. The master is a lite weight Chrysler unit with the Lamb no drop out rod. The local NAPA store did not show any. I will look at the dorman site to see if I can find some thing. Thanks for all the help. Tom

Re: Master Cly Install Help
 

They are a 20 thread...That is exactly the problem!

Re: Master Cly Install Help
 

John do you know what year they are off of, lots of old salvage yards in my area that I could look for. Thanks Tom

Re: Master Cly Install Help
 

Allstar performance has flare nuts with 1/2-20 thread for 3/16 brake line, p/n all50114 and 9/16- 18 thread for 1/4 line, p/n all50119. They also have adapters for 3/16 brake line to those threads. I beleive summit and jegs carries Allstar performance. Allstar performance is the house brand of Lane Automotive and Motor State distributing in Watervliet. Mi

Tom - Don't know about Lamb, but Strange recommends using the rear port to the brakes which require the most volume. Using four-pistons front and rear on ours I just plumbed as usual with the rear port serving the rear system and used a 2lb residual valve in that line.

Re: Master Cly Install Help
 

I will check with Lamb on Monday, this is turning into a real search to find fittings to get this to work and look nice. Spent most of the day looking for stuff when I could have been working on the car. Like I said before it worked fine with the stock master cly and now I try and make it better and struggle big time. Thanks to all Tom

Tom, the Dorman number for a 1/2"X20 nut for 3/16" tubing is 490-302. For 1/2"X20 1/4" tubing it's 490-305. In the link I posted earlier they are refered to as 'Oversize Tub Nuts'. The 'oversize' refers to the fact that the nut is larger than the normal brake line nuts for a specific tubing size. -Al

Re: Master Cly Install Help
 

I found some short lines with the big nuts on one end, and regular line nuts on the other. Pep Boys had various such lines.

80s Dodge full size PU havr them

The Cylinder I use is proportioned 69 Front and 31 Back

Re: Master Cly Install Help
 

Would the BR-150 and BR-155 tubing nuts from the SUR & R company be the ones
Tom is looking for? If so, available from some auto parts stores...as well as Summit
Racing.

Re: Master Cly Install Help
 

Got it covered today with a call to Roger Lamb [great people] but he did have to go dig for them. Also on my app rear line goes to front brakes front line to the rear. I want to thank every one for your help. Tom

Re: Master Cly Install Help
 

Tom, does this mean we'll see you out this year?

Re: Master Cly Install Help
 

Napa/Gates Part #G49504-0303 adapts 9/16-20 to 3/16 female inverted flare.
I know you got it solved already, but thought I would put the info out there for future reference.
