Need a vacuum pump (brake) due to low vacuum. Are there ones better then others and do you have pics on where you may have it mounted. They are an eye sore and trying to make it less noticeable.

Tell us why the "need"
in practical real world....u brake while moving correct?
If stopped, then u have a hard brake, but good, if u pump the brake pedal a couple times.
When u are slowing down at speed the rpms are up..good vaccuum, and to make even better, using engine brake...real good vaccuum.
The only place where in thr real world u may notice it is when idling out of a gas station, and touching the brakes...at walking speed or less, and they go hard, but still have good brakes...at walking speed.
Or rolling down a slope at idle speed...same thing.
I have driven several 100K mikes with low Vac on a daily basis.
This is one of those 'issues' that is not an issue, but the marketig and propaganda guys see an opportunty to screw some dollars into their pockets.

When you drive a high performance, big cam car youy want to make sure the brakes "are there". I have driven my car out of drive way on a few occassions and coming up to the stop sign, I'm pumping the brakes to try and stop and it bothers me let alone wanting to floor the car and "hope" I have the breaks to stop in a reasonable amout of time.
Pump them???
All it is that there is no vac on the brake assit and basically a solid brake pedal not much different to manual brakes....
?If u have to pump them then there is something very seriously wrong with your brakes and it is NOT the power assit
If I had to pump then I would be to....but the arguemrnt doesnt relate because as soon as the rpms and speed gets up u have vaccuum and u have engine brake and power assit brakes like any normal car... your "hope" is just not applicable in practice or theory, but based on u having to pump the brakes with no VAc
a car with no vac on power assit, the pedal is significantly higher and a damn sight harder.
i installed the ssbc pump on my 69 z/28, i managed to hide it on the driver side inner fender, behind the washer bottle. its almost unnoticeable... until i turn the ignition on... the noise it creates is very noticeable.
on a postive note, i have more then enough vacuum.

Bob, if you have power steering check this out. Someone else posted it so I can't take credit.

I installed the SSBC pump on my buddies 69 camaro. I mounted it the same place as Erick. I made a plate for it to sit on and bolted the plate to the fenderwell. I also painted it all black so you could not notice it as much.
It comes with a relay and vacuum switch that turns it off and on so it doesnt run all the time.
On my 69 I have the GM diesel factory pump. Because diesel cadillacs never had vacuum. They dont make them anymore. I mounted mine on the firewall between the drivers fender. You cant see it but if I have to change it,, the fender has to come off.
I hooked my relay to the brake pedal switch. When you hit the brakes my pump comes on.
I also just installed the hydroboost on another buddies car. It has alot of lines and very costly if you get the braided high pressure lines. It does work good though.

X2 on the pumping. All the booster does is give you easier pedal pressure.
I fool a lot with brakes and unless you have a Monster cam with less then 6-8 inches of vacuum at idle the big booster should work fine. You can also use a smaller dual diaphragm booster.
I find often that guys are using the wrong bore size MC for their applications as well.

Mu manual 4 wheel disks work just fine. If the master cylinder is matched correctly there is no problem. If you had working power brakes and then added a cam that lowered vacuum, the piston is now the wrong size to give you the proper braking. Change the master to a manual master and you should be good.
I think you are RIGHT!
I bought an SSBC frt brAKE kit then a retro cadi brake kit or whatever from someone on EBAY and brakes SUCK s h i t ! even with vac pump turned on it still takes a couple pumps for things to be right so master:beers:
:beers: cyl MUST be wrong too ! I want to scrap power brakes for manual because I just WANT brakes and my wife can live with it for the 2 or 3 times a year she drives it !

I want to scrap power brakes for manual because I just WANT brakes and my wife can live with it for the 2 or 3 times a year she drives it !The stock big booster is fine down to 4 or 5 " then one gets the idling acroos a gas station hard pedal...not loss of brakes but manual brake.
And yes a smaller booster certainly helps.
As to bore etc..no..the issue is with the vac inside the booster and the assit it provides...eith the vac and assit is there or it is not.....before the pedal is pressed the 2nd or 3rd time.
This is the casre with the small booster to....thinking a change to small booster will mke significant difference thu...dont bother wasting your time or money.
If u have a vac gauge in the cabin....and bother to take notice of if.....WOT and idle/ off idle rpms are the only times u have low vac
you dont use brakes at WoT and at low rpms/ walking pace, manual brakes are not an issue.
And if u have a big track cam on a street car..that generally means getting serious track time....which means u dont go ading stuff/weight u dont need.
And if u have a big cam..IF the car is set up right u also have high gears 3.7s or 4.1s plus...which meand at walking pace u have higher rpms anyway, so in many cases it will be border line as to the manual brakes.
