'63-'66 Power Brake Booster Bracket With Hydraulic Clutch Conversion

This kit converts your ’63-’66 Chevy or ’64-’66 GMC truck to power brakes and also a hydraulic clutch. The brake booster part is identical to the standard booster brackets that I make and bolts to the firewall using factory threaded holes. Consequently the same compatible boosters will fit as well as the hydroboost mounting plate that I also make. The booster bracket is fabricated from laser cut 10 ga mild steel, Then formed and TIG welded on the outside and MIG welded on the inside. The clutch master cylinder will be a Wilwood master cylinder sized to work with the particular clutch slave cylinder or hydraulic throw out bearing that you will be using. The linkage assembly parts are all zinc plated to resist rust. Included in the kit is everything shown in the picture below.

To install the master cylinder you will have to drill (2) 11/32" holes for the mounting bolts, and a 1 1/2" hole (with a hole saw) to accomodate the center of the master cylinder. The supplied standoff simply bolts to your brake pedal using an existing hole. Then the clutch master pushrod with a clevis connects to the lever arm and another clevis with the threaded rod and heim joint bolts to the standoff on the other end.

The cost of this kit will be $260.00 plus a flat rate shipping cost of $22.65. Satin black powder coating is available for an additional $10.50. This pricing is always current and up to date.

To purchase yours either post in this thread, send me a PM or send an email to captainfab454@hotmail.com, and I will give you the ordering and payment instructions and current lead time.

Re: '63-'66 Power Brake Booster Bracket With Hydraulic Clutch Conversion

When you say 'stock type s-10 clutch parts' do you mean the clutch slave cylinder? If so, I don't see that being a problem. I would just need some more detailed info so that I supply you with the correct clutch slave cylinder.

Re: '63-'66 Power Brake Booster Bracket With Hydraulic Clutch Conversion

Here are a few pics of the linkage between the clutch pedal and clutch master. This linkage assemble allows you to have full travel of the clutch pedal and limits the stroke of the clutch master so as to not bottom out the piston.

Re: '63-'66 Power Brake Booster Bracket With Hydraulic Clutch Conversion

I have a 63!gmc with a hyd clutch already from the factory. Would like boosted brakes. Would this clutch kit work?

Re: '63-'66 Power Brake Booster Bracket With Hydraulic Clutch Conversion

No, you will want the booster bracket and kit for the '60-'62's. The GMC's had the same design '60-'63 whereas Chevy used it for '60-'62 only. Here is the for sale thread for the one you need.

http://www.67-72chevytrucks.com/vboa...d.php?t=362375

Let me know.

Re: '63-'66 Power Brake Booster Bracket With Hydraulic Clutch Conversion

Here is a list of the compatible brake boosters.

'67-'70 pickups, Suburbans, Blazers (If staying with 4 wheel drum brakes)
'70-'74 Impala, Caprice
'80's G body Vans (full sized)
Early Astro/Safari vans with the vacuum booster
'82-'02 S10/S15 pickups and Blazers
'88-'98 full sized pickups
'92-'98 Suburbans, Blazers
Any GM hydroboost unit, with the addition of my hydroboost mounting plate.
Most aftermarket universal boosters have a square pattern and will require slight elongation of the booster mounting holes in the booster bracket

There may be some other applications, and/or years, but these are the ones I have been able to verify.

Re: '63-'66 Power Brake Booster Bracket With Hydraulic Clutch Conversion

I hear you Cap!

I am about to look at this soon and may need your kit for my '63. It looks well researched and planned.

Re: '63-'66 Power Brake Booster Bracket With Hydraulic Clutch Conversion

Capt, will you post a picture of the engine bay side please??
Also, with the original pedal assembly out, is it possible/advisable to dissasemble and rebush the pedal pivot shaft? Mine seem ok but are 53 years old. (I'm about to derust in the electrolytic tank.)
are there parts available to do this or would something have to be fabbed up?

Re: '63-'66 Power Brake Booster Bracket With Hydraulic Clutch Conversion

Sorry but I do not have any installed pics of this conversion kit other than what is already in this thread. This conversion is basically the same as the '60-'62 kit shown in this thread. There are some engine bay side pics in that thread.

http://www.67-72chevytrucks.com/vboa...d.php?t=362375

I believe either LMC or Classic Parts should have the necessary parts to re-bush your pedal pivots.

Re: '63-'66 Power Brake Booster Bracket With Hydraulic Clutch Conversion

Yes, thanks for that lead...LMC does have the clutch pedal plastic bushings.

I am sending a PM to order a bracket kit!

Re: '63-'66 Power Brake Booster Bracket With Hydraulic Clutch Conversion

If you are talking about the linkage assembly, yes I do sell that separately. It is $100 plus shipping of $6.30.

Re: '63-'66 Power Brake Booster Bracket With Hydraulic Clutch Conversion

http://67-72chevytrucks.com/vboard/a...1&d=1310359367

I thought I'd feed this back publicly, not to find fault with the product but in case anyone else has found a similar issue.

On the kit you sent out to me the block that is fixed through the lower clutch cylinder bolt is different - see pic below. I'm guessing that this is simply product refinement



The issue that I have is that using the format as set out in your guidance pics the plunger rod for the clutch is pulled downwards instead of straight outwards.

If I alter the format as shown in the pic below then the plunger rod sits straight and the rod from the clutch pedal pivots on the middle hole of the plate that unifies all three rods. To make that work, the plate has to be filed.

Also, the extra cut plate that sandwiches between the clutch cylinder and the firewall renders the bolts too short. Is this plate simply for reinforcement or to help with pedal travel? See pic below:

Re: '63-'66 Power Brake Booster Bracket With Hydraulic Clutch Conversion

Capt will answer for himself, but if this helps speed you along...run with it....on the pushrod, it is not how level it starts, its that it needs to be level at full insertion.
On the top bolt, yes, same thing here, I just used and turned around a slightly longer bolt, inserted it from inside the cab, and put the nut on the outside as it was too long to insert from the master side and clear the pressure line fitting.

Re: '63-'66 Power Brake Booster Bracket With Hydraulic Clutch Conversion

The different pivot block than what is shown in the pictures was done from a manufacturing perspective to keep costs under control. I simply do not have time to mock up another assemble just for pictures.

The spacer between the master and the booster bracket serves as 2 purposes. 1) It increases the clearance for the wire harness that is beside the clutch master. 2) It eliminates the need to shorten the clutch master pushrod.

The configuration of the clutch linkage assembly is designed to work as it is in the pictures. This allows full clutch pedal stroke without bottoming out the clutch master. What you have done just reversed that feature. The clutch master will bottom out before the clutch pedal. This could very likely damage the clutch master.

As for the bolt length. You are using the wrong bolt. As Heater63 stated, the top bolt must be installed from inside the cab, with the nut on the engine side of the firewall.
