Merle Coggins Posted June 16, 2008 Report Posted June 16, 2008 I've been pondering something lately and I'm hoping some of you guys can confirm or deny my ponderings. As has been mentioned on these pages in the past, the brakes on cars use twin cylinder brakes up front and a single, double acting cylinder in the rears. This is apparently due to wanting better stopping power up front. However, on the trucks (at least on Pilot-House trucks) they used the twin cylinder arrangement in the rears, and a single, dual acting, cylinder in the fronts. This is probably due to the fact that when fully loaded (Job-Rated) you need more brakes at the rear. Now for my question... Would it be possible to use the front brakes from a car on my truck? I know most everyone will say that it would be more cost effective and feasible to put discs up front, but remember I'm just pondering. It's just an idea to keep the originality of drum brakes with a little more stopping power. What size are the front brakes on the cars? My truck uses 11" X 2" brakes. If a car uses 11" brakes as well, and the backing plates would fit the truck spindles, I'd think it would be possible. Any thoughts? Merle Quote
Young Ed Posted June 16, 2008 Report Posted June 16, 2008 Merle the cars are 10in brakes. Besides that I bet they would fit. The drums on my truck are the same as car ones but I only have 1 WC at each corner. Quote
Merle Coggins Posted June 16, 2008 Author Report Posted June 16, 2008 Yea but... if I switched to the 10" brakes, I'd have to switch drums. My drums have studs with nuts rather than wheel bolts. And I'm pretty sure the bolt pattern is different than the 1/2 tonners, and maybe the cars too? I was hoping that maybe the bigger cars had the bigger brakes too. Merle Quote
greg g Posted June 16, 2008 Report Posted June 16, 2008 I believe the larger cars have 11 in front brakes. As far as I know they were all 5 x4.5 lug spacing. Check on the imperial club wesite, they have most of the mauals available in their tech section. You might be able to tell by reading through the brake stuff over there. Quote
Young Ed Posted June 16, 2008 Report Posted June 16, 2008 Ah you have a 3/4 ton don't you? So you have 5x5 bolt pattern instead of 5x4.5. Pretty sure that is unique to 3/4 tons. Quote
greg g Posted June 16, 2008 Report Posted June 16, 2008 I believe the big chryslers were 5x5 also. Quote
