2011年1月9日 · Well the title said it all, but anyways. Here´s an example. My low vacuum bb car needed new brake booster.

Weak Brakes - 9" single booster vs. 8" double booster
2010年4月28日 · It was updated with a disc brake conversion kit. I have a 9" single diaphragm booster and 11-10 in/hg in gear. I've been told power brakes should still be effective at this vacuum level. I also have a vacuum canister hooked up. Does anyone have real world experience with an 8" dual diaphragm booster and vacuum at this level?
Brake Booster Recommendation (9" dual diaphragm)
2016年6月17日 · Well, I haven't seen a 9 1/2" (mostly 7", 8" and 9" dual diaph. boosters). I have a Vette 4 wheel disk master cylinder that I'll be retaining from my old front/rear 11" disk brake setup. The booster I currently have is an 11" single diaphragm (Baer said to ditch that one). Let me know what y'all have used.
Dual diaphragm brake boosters - Team Chevelle
2006年6月11日 · An 8" dual booster should have about the same boosting effect as an 11" single. area of 11" diaphragm=95 sq in. Area of 8"=50.2 sq in. Add a second diaphragm of 50.2 sq in and you have a total diaphragm area of 100.4 sq in. That is not a big difference in area, so I would expect not much diff in performance.
What dual diaphram brake boosters can I use on my Chevelle?
2003年6月1日 · To achieve peak performance with such systems and a modern, high-tech look, it’s best to install a late-model dual-diaphragm power booster.

2021年4月6日 · I'd stick with an 11" if you can. An 11" provides more psi than a single diaphragm 9". I haven't seen a dual diaphragm 9" that is made for A bodies. If you can find one with the correct mounting bracket, it should provide about the same psi as a single diaphragm 11", if you need the space for your valve cover. But your lines would need to be ...

7" dual Diaphram Brake Booster VS. 11" - Team Chevelle
2005年3月15日 · This setup did not really have a "proportioning" valve. It does have a distribution block with brake failure switch in it. It also has a barrell valve to delay application of the front brakes. I recently converted over to a dual booster from a 79 El Camino, probably a 7" or 8" size, for clearance with the BB and tall valve covers.
