Adding Power Brakes to a Ford F-100 Firewall

Adding Power Brakes to a Ford F-100 Firewall
When it comes to building a vehicle from start, there are certain things that are authoritative, and certain things that have to be done in a set arrange. Of farthermost importance is that it is comfortable to drive. Unless you ‘re building an absolute appearance car, you have to be as comfortable behind the bicycle as potential. This means the home has to be ergonomically planned out from the beginning. The seat position has to be comfortable, and the pedals have to be a comfortable position from the floor and easy to reach. Likewise, the steering steering wheel must be comfortable to use. Are the gearshift and all the switches accessible with a seat belt on ? All this will depend on your stature and size, and should be adjustable, if possible, if anyone else is to drive the vehicle. While appearance is a big part of what we do, ergonomics in the cockpit is vitally authoritative if you plan to drive any serious distance. Having determined the best position for the guidance wheel, and hence the column in last month ‘s issue, the next order of occupation was to install a brake and clutch pedal that met our parameters — to work properly, have sufficient travel, look adept, be the ideal altitude from the floor, and be in the best position side-to-side.

The first gear three points were easily sorted, as we opted to use a cosmopolitan through-firewall brake and seize pedal assembly from Kugel Komponents, with their round pedal pads. The fourth orient was easily solved, as we long ago determined that having the center of the pedal point pad 8 inches from the floor was ideal for us. You may prefer different, indeed simply measure your casual driver or whatever cable car feels comfortable to you, and use that measurement. All of which barely left the side-to-side aligning remaining. The ideal stead was to have the brake pedal on the correctly of the column, and the batch on the left field, but we hit a rip. In order to facilitate removal of the valve cover, the supporter had to be a certain distance away from the engine on the outside of the firewall. We could n’t change the height as it would mean changing the acme of the pedals inside the taxi. The swage lines in the firewall besides allowed us limited options, unless we removed them and went with a compressed firewall, as both the bracket and the booster bolt up to flat surfaces. Given that the position of the promoter allowed us to mount the pedal fabrication bracket on a flat section of firewall, that was the easiest option, though it meant the pushrod for the booster, and hence the brake pedal, was directly above the steering column. We could have heated and bent the bicycle, but it would have ended up shorter than the batch pedal point, and affected the built-in pedal proportion. alternatively, our solution was to take the pedal back to Kugel Komponents and have them weld another bicycle far to the right on the pivot shaft, and then trim the original bicycle so the upper section, operating the pushrod, remained. A arrant solution ; we now had pedals where we wanted them, they looked good, however placid worked as intended. We should point out that the Kugel pedal assembly is designed to be a universal meet, and in the majority of cases is just that, but it ‘s decent to know they are prepare to make minor modifications if required. away from the modified pedal point, our assembly works precisely a designed, and works great. Kugel Komponents will curtly be offering counterbalance pedals as an option. With the pedal forum mounting process, we cut the holes in the firewall for the passkey cylinder pushrods, allowing us to move on to the upper goal of the brake system, namely a Wilwood dual bracken overlord cylinder, mounted to a 7-inch booster, and Wilwood clutch dominate cylinder. We besides installed Wilwood ‘s recently introduced Combination Proportioning Valve Mounting Bracket Kit, which includes the valve, bracket, hardware, and pre-bent stainless steel steel lines, making facility both a cinch and appearing professional. 01 The standard steering column passes through the toeboard, but so does the stock brake pedal. We ‘re going to change that and modernize our Effie. 02 Kugel Komponents offers respective different styles of pedal point assembly, from through-firewall as shown, to 90 degree and even 180 degree. The latter two put the master cylinder inside the cab for a clean underhood appearance. Brake only or brake and clutch assemblies are available. Both pedals pivot on a common beam, using nylon bushes. 03 Our first mock-up side placed the brake and cling to pedals on either slope of the steering column. Ideal, but it placed the promoter besides near to the engine to enable the valve covers to be removed, and the swage lines in the firewall would make mounting the assembly awkward. 04 We tried mounting the pedals with both on the leave of the column, but not only did it look and feel curious, the swage lines in the firewall again made mounting the assembly difficult. 05 The assembly fit absolutely on this bland section of firewall, and the booster besides fit here perfectly excessively, then once the pedal point acme was determined, we drilled the firewall, using the bracket as a template. We ‘ll show how we overcame the bicycle placement problem in a moment. 06 The bracket bolted in place, along with the supporter. We used hole cutters as close to the size of those in the bracket for the booster and batch cylinder holes in the firewall. The clutch hole has however to be cut.

07 The solution to the bicycle problem was to use another bicycle and weld it far along the shaft, but retain the top section of the original to operate the maestro cylinder/booster ( where the clevis pin is ). 08 Kugel Komponents have performed this change before, and were happy to do it for us. While the pedal bracket is universal joint, we had to be awkward and want it modified ! 09 here ‘s the resultant role, with the master pedal modified to leave the upper section. This means the actuating perch aligns with the booster/master cylinder as intended, but our pedal point now clears the steering column. 10 Kugel Komponents offers several styles of bicycle pad. We opted for this beat style, with a ridicule rubber insert. The pedal slog mounts allow the pads to be angled to suit. 11 An total bonus of the bicycle pad mounts is that we can choose between mounting both pads offset to the proper of the pedals 12 or offset the brake pad to the forget, positioning the pads closer together if desired. 13 The finished assembly ; our pedals are now on opposite sides of the column, the bracken pushrod however passing through the firewall where we wanted/needed it to be. Note the batch master cylinder is nowadays in place. The Kugel assembly is designed to accept a mechanical brake faint switch on the upper part of the bracket, though we have a pressure switch over on the Wilwood proportion valve. 14 We used an 8-inch double-diaphragm supporter, besides sourced from Kugel Komponents, and partially of our pedal fabrication location problem was that we wanted to be able to remove the improbable valve cover on the Roush small-block Ford with the booster in set to facilitate alimony in the future. Note a small section of the firewall brace had to be removed for headroom. 15 As we ‘ll cover in a future installment, we ‘ll be using Wilwood phonograph record at all four corners. We besides sourced our victor cylinders, proportioning valve and bracket kit from Wilwood. The bracket kit is designed to install their valve on their bicycle-built-for-two master cylinder, using pre-bent stainless steel lines. 16 After searching through the boxes for the brake organ pipe fittings and blanking plugs for the dual-sided master cylinder, we discovered that Wilwood ships them inside the master cylinder ! 17 A pair of blanking plugs are included therefore you have the option of plumbing your brake lines from either the leave or right side of the cylinder. We used the 12-20 to 38-24 fittings to plumb the proportion valve. Note four crush washers are besides included. 18 We installed the blank ballyhoo on the engine side of the master cylinder. 19 The 12-20 to 38-24 adapters were installed in the dominate cylinder before the pre-bent stainless steel lines were installed. 20 Included in the kit are these spacers that have to be installed before the proportion valve bracket is fitted, to allow it to clear the rib on the maestro cylinder body. 21 Stainless Allen-head bolts are supplied, to mount the valve to the bracket.

22 More stainless steel hardware holds the reservoir top in place. 23 The completed installation in the engine true laurel, including the batch dominate cylinder. All that remains now is to install the brakes and plumb the lines. Sounds easy said promptly !
