Master & Booster Angle

[OhOneWS6]

Local hot rod shop seems to think there is an issue with the angle of my master cylinder. It is lower in the front. I realize this is a Corvette style master. I am doing a 4 wheel disk conversion. The stock master was at the same angle. The booster and bracket are stock. This is a factory power brake 72 1/2 ton LWB Cheyenne Super. Does it look like this booster and bracket are installed correctly?

it's normal ... the local hot rod shop has a lot to learn ...

[OhOneWS6]

I had never considered that it was wrong but when it was mentioned I thought I better research it a little further. No need to name the shop. They are reputable. They have been around for a long time and put out some very high quality work.

Don't take this wrong. I agree with you Shane but If I could hear it from a few other members or better yet see a few pics of other stock boosters it would make me feel better.

[Shane]

No offense taken and I would do the same.

If you need a pic I can post one LATE tonite or later in the weekend...it looks about right, maybe a tad bent but looks ok to me

Here is mine on my 69. It tilts forward the same as yours.

[mbgmike]

Thats cause you bought it from CPP instead of us
its normal

[my67c20]

I asked the same thing when i reinstalled my part. They were not tight but leaned forward even less after i tightened everything up. My opinion says it is okay.

I just went out and checked the 72 burb and it looks about the same as yours.

From the top of my head, one of the first thing i noticed on my 68 was the angle , yes its normal .

[71 super]

Normal, it looks even more severe with a bendix master cylinder

[Sammy]

I'm using a corvette MC it sets the same angle for almost 2 yrs. Leave it be.

[OhOneWS6]

Thanks guys. I am convinced.

[GASoline71]

Yep... completely normal.

i just put a 7 inch dual diaphram booster on my 67 and it is tilted slightly but maybe not as much as yours. i would think that it is ok. i did mount the proportioning valve on a bracket on the firewall.

[68 TT]

They tilted all the power brake master cylinders in that time frame. The cars have a severe rearward angle to them.

Don't know why they did it but it is normal with power brakes.

I was planning to convert my 67 to power brakes. I was going to use a gbody booster and cylinder but realized the reservoir was designed to sit level when the firewall was at an angle in the "upwards" tilt which is opposite to what's posted above. Then I look at this thread from hit rod and I am really confused..

My original drum/drum setup had the master pretty much dead level. You're looking at a car setup with the thing angled that high to clear the engine. my aftermarket disc brake upgrade has the master pointing down at a slight angle, not level like original. Just look at the different setups in this thread, and I think you'll realize that you have nothing to worry about.

The stock location of the power brake booster and m/c always bothered me. I'm going to try a Capt. Fab. bracket and see if it will clear my shift linkage under the hood. This will make the m/c level and closer to the firewall and a lot more out of the way. Should be mocked up by the weekend and i can give a better answer.

I'm running a wilwood setup (master, Prop Valve, spindles, brakes, rotors, etc...) and it's pretty tilted.

So much so, I'm seeing coating damage to the master from front edge brake fluid spillage. (not to mention the rear compartment isn't as full as I think it should be in this configuration)

I've been thinking about putting some washers at the firewall studs to level it out some, honestly.

[OL SKOOL]

I had enough time to mount the booster m/c this will give you a general look at it. The factory mounting and linkage bracket points the m/c down on power brakes. Like Steeveedee said the non power m/c set level thats what mine came with. The 11" booster might have a clearance issue with the column shift linkage. Maybe that's what the factory came up with for the clearance issue? The set up you have under the o/p hood looks right.

I had the stock set up on my truck. My problem was I couldn't get the valve cover off with the 11 inch booster. It was about a 1/4 of an inch away. I have roller rockers and some times need to get to them with out taking the brake booster apart. I installed the 7 inch double diaphragm booster and a Capt. Fab bracket. Works fantastic.

I have the same Wilwood setup as bigtop. I got it from classic heartbeat. It sits at the same slight downward angle.
