Re: What kind of brakes does your bus have?

Air... and that very annoying buzzer. Back when David & I first met, I had an alarm clock with the same annoying buzzer, but slightly higher pitched. We woke up every day it went off with a headache. Took us a while to figure out it was the alarm clock. I bought a new clock. I really dislike that buzzer.

Where was your buzzer located?

Ours is a 12 row '88 International Blue Bird with steering assisted disc brakes. Smooth and firm.

Jasmine will have air brakes. I won't even consider a bus without them.

As a former long-haul truck driver I know the ins and outs of using air brakes, and in a pinch can get down there and work on them a little bit if needed.

I now have 1 of each,

my air brake bus is 4 drums, my hydraulic brake bus is disc front drum rear..

I feel like in a hard stop situation my air brakes react faster and i have more control over precise braking..

the hydraulic brakes hit hard, there is a definite time for the poedal to travel down before good engagement.. in hard braking even a 1/2 or 3/4 of a second can mean stopping soon enough vs not..

I believe air-brakes in a failure situation are much safer.. hydraulic if you lose pressure, pedal just goes to the floor and you have to manually react with emergency brake..

air brakes you get automatic spring brake engagement on brake failure of pressure...

I noticed my hydraulic one is hydroboost with a little motor to run the hydrooost if the engine dies.

^^^ THIS ^^^

I will never own anything larger than a pickup again with hydraulic brakes.

My first rollback truck was an old Ford F700 with a hydroboost setup. I bought it it put the body on a newer truck, but decided to run it for a little while until I had time to do the body swap.

I had just finished dropping off a 10,000 lb excavator at a demo job, so luckily the truck was empty when it happened, but a rusty brake line burst as I was pulling up to a stop sign at the top of a hill.

It was an old single chamber master cylinder, so I lost all brakes. I had engine braked down to almost stopped, hit the clutch and shifted into neutral, and then was hitting the brakes just to keep from rolling backwards at the stop sign. By the time I realized what had happened, I was traveling too fast backwards to get the transmission in gear. I grabbed the parking brake lever, but it was just that, a parking brake and not an emergency brake. It didn't have enough to even put up a semblance of a fight against the momentum that was quickly amassing.

Luckily there wasn't a car behind me when it happened, so I didn't run over anybody. I changed lanes while rolling backwards so I was at least travelling the correct direction for the lane I was in. It's a good thing I did, because I ended up doing about 35 backwards down that hill and had two cars pass me in the other lane before I rolled to a stop about half a mile later on an uphill slope. Dropped it back into third, drove back down that hill, down-shifted and turned back into the demo job I'd come from. Turned the key off with it in first gear and called my wife to bring me a clean pair of pants.

Air brakes. The only way to go.

Hydrolic brakes are not actuated by atmospheric pressure, I believe almost all of them use vacuum from the intake manifold.

For must of us, if we had to get a brake job done once on our skoolie, those new brake shoes would last longer than our bus. Re-shoeing a bus with air brakes is actually quite simple.

You can't beat the stopping power of air brakes! They are far superior to hydrolic. If they we'ren't better, semi-trucks would all use hydrolic brakes. A kid can press the brake pedal hard enough to lock up all 6 wheels in a bus with air.

It's super easy to adjust air brakes, it takes about 10 minutes total to adjust all four. I do this once every couple months. (I plan to do it a few times on my 5k mile trip across the USA) IF part of your air brake system fails, parts are readily available at any truck repair shop. Air brake parts are nearly identicle for all big trucks/buses.

One huge safety factor with air brakes: If the system ever failes, your bus stops! If your hydrolic brakes fail, better hope you don't need to stop in a hurry.

Who says a skoolie shouldn't go over 45?? I do plan to get to my destination before I die! Most skoolies don't go much over 55 which is a perfectly acceptable speed.

An added bonus is the availability of compressed air for filling tires, or utilizing air tools, and of coarse using those new air horns.

I appologize for being so argumtative, I"m cranky today!
Enjoyed hearing your arguments, I am thinking that this will be the direction I go since I am needing to replace the system that sat for 15years with being maintained or even ran. The clutch pedal is a big ol floppy chunk o stwel at this point and the brake pedal has frozen solid. qould a junk yard be a place to look for parts if I know what I need to find and the condition that it "should" be in?

I have chevrolet Hydro-vac brakes. My brake lines need to be replaced. I have 2 frame mounted boosters and 2 vacuum tanks. My question is can my system be up graded to Hydro boost? I don't want air brakes because I would have to get a higher classification on my drivers license.
Thanks Gordon
