But I can't find it!. I even can't find the search!.
Hi guys/gals:
Correct me if I am wrong please:
1- Brake booster from 73-87 doesn't bolt up to 67 pedal set up. If this is correct, how hard is it to modify it?
2- master cylinder from 73-87 does bolt up to 67 booster.
3- Brake line fitting are different between 67-72 and 73-87.
The reason for all these is the cost. I can get the whole booster and master cylinder for 73 and up for under 140$ with life time warranty versus 300$ something. I am converting to front disc and it is 3/4 ton.
Thanks

You can get a complete replacement for the 67-72 from napa for like 170.00. They sell boosters alone for about 140, and master cylinders were like 40 or 50. Check their web site.

thats some crazy eyes !!!

68C15 · 06-22-2005, 07:36 AM

you are correct on all 3.
I found this out myself. but I didnt let that stop me. I modified the booster bracket to fit the 68 firewall, grafted together the 68 pedal top (where it swings from under the dash) to the 73-87 bottom using all but the top 3 inches. then ran new lines from the master to the later combination valve using the correct fittings & then flaring the lines myself. it all works pretty darned good

Wow, why are they so much cheaper than all the chevy part places? chevyduty, brothers, gmcpauls are all about $300-$400

Nima · 06-22-2005, 01:25 PM

Cool. Thanks for info. When I use napa online on their 67-72 chevy section they don't have any truck to chose from!.

hgs_notes · 06-23-2005, 11:06 AM

Nima, you have to chose "chevy truck" from the manufactures list, not just "chevy".

HG

Davy · 06-23-2005, 11:31 AM

you will also need brackets and I think a different rod to the pedal. These aren't available from Napa.

70GMC_BOB · 06-23-2005, 11:48 AM

find the place that they get thier brake parts from. In seattle I buy all my brake parts rfom olympic brake supply who delivers to napa/schucks/ect. and save about 30%. When i had my burb and replaced everything except the rear drums and front rotors a save mucho dinero$$$. another plus is thier counter guys actually know what they are selling.

uuhhhh!!1, I feel dum now!. Thanks. I should pay more attention.

70GMC BOB, do they have any phone # or web site? or do they have any place in Ca that you know of?

So far, to avoid any modification on my pedal set up, I came to this conclusion: Buy a booster for 67 (80 to 85$), 73-87 master cylinder which suppose to bolt right up (30-55$) and get the new pp vlave. This way the whole thing should stay close to 150 to 180$. Ofcourse I need new lines too. Please correct me if you see anything wrong with this method. If this is ok, this way other people can save some money too. Thanks
