1957 Chevy Grumman Front Disk Brake Conversion
I usually stay on the 60-66 side but recently picked up a 57 Chevy Grumman van and was wondering what is the best way to convert the front to disk brakes.
Is the van front axle the same as a 3/4-1 ton truck axle? Any good disk brake kits? I want to keep the stock 19.5" Wheels. I found this bracket kit. Any opinions on it? Will it push the wheels out to far? http://www.thehollisterroadcompany.c...converion.html I have a 2003 Chevy 2500 van rear axle with disk brakes and 3.73 gears so just need to figure out the front. Thanks

Re: 1957 Chevy Grumman Front Disk Brake Conversion
That hub uses our SRW kit. Its a standard single rear wheel front axle. On the dually truck there is an extended hub that sticks out about 6" from the drum.

Re: 1957 Chevy Grumman Front Disk Brake Conversion
Okay thank you for the reply. Before I purchase I need to do my home work on the other parts I will need.

Re: 1957 Chevy Grumman Front Disk Brake Conversion
Why do you need the discs? Again, I have to ask the question. Unless you are driving a lot on winding mountain roads you do not need disc brakes.
Forget all the "modern highway" BS you don't need disc brakes unless you are driving it on windy mountain roads or something like that where the drums get overheated. Just normal driving you don't need them. Brian

Re: 1957 Chevy Grumman Front Disk Brake Conversion
hey Brian, have you ever had to hit the brakes after one wheel goes through a big puddle, or both for that matter. not as good as discs plus they tend to pull. if it was me it would be discs already. haha

I have to ask, what happened 40 or so years ago that changed everything? 40 years ago about 95% of the cars on the road were drum, it wasn't that many years before, 1970 or so where about 99.9% of the cars were drum. How did we survive? There must have been crashes on every street every day. Nope, there weren't, how in the hell did we survive. Brian

The safety enhancements of disc brakes over drums are well known. The main one is if an outer wheel bearing fails on these trucks the wheel does not come off if its a disc brake. Disc brakes stop better with less maintenance, They don't fade in weather like drums and with the 2003 up parts this kit uses you can replace them in 10 years if you need to. Towing with a big van like he has its just a plain smart decision. Keeping up with traffic I one thing but you also need to be able to stop with traffic. |

Re: 1957 Chevy Grumman Front Disk Brake Conversion
It looks like the windshield is made up of 6 pieces? A flat piece at the center and then a curved one with the flat one on the sides?
If that is the case those flat ones will be easy to change. The curved ones are a while different story but if you had the flat ones new it would be what you are looking threw most of the time and it would make a big difference. Brian

Re: 1957 Chevy Grumman Front Disk Brake Conversion
I saw a few videos on how to make those out of Lexan. Seemed to be moderating easy but time consuming

Luckily I found a guy on eBay who sells the curved corner piece in Plexiglas for $75 each. Already received it and it looks good. The body is straight with just a few small dents and scrapes down the side.

Re: 1957 Chevy Grumman Front Disk Brake Conversion
I wonder if a hydroboost could work for the brakes. it would take less physical space.

Re: 1957 Chevy Grumman Front Disk Brake Conversion
easy peasy to get a mc in there
leave the pedals as are (clutch is optional ) cut off the old mc (leaving the pedal mount) and make a bracket to mount the new mc or hydroboost a foot behind the old mc make a new rod to connect the pedals to the new mc look at orrieg's build for ideas, my hydroboost is at the pedals, it is a little tight to everything orrieg has his mc 1 ft behind the pedals

Re: 1957 Chevy Grumman Front Disk Brake Conversion
It is a "Shorty" at 104" or 108" (still need to measure it) and that is the reason we bought it.
