G,day guys, I put a 7" booster on my 50 ford to clear cal-custom style rocker covers on a cleveland . Problem being the booster **** it's self in no time flat, are all these boosters more chinese **** or is there a good brand available. Good captian.
They all look like they come out of the same place to me. Can you elaborate on '**** itself' please, maybe there's more to it?
I have never been a fan of any of the aftermarket power boosters. The duals are a bit better in fuction than the singles, just ugly. The same problem exists with all of them and has to do with the way the booster works. Just about every one of them will give you an aggressive amount of ***ist at light pedal pressure with the ***ist tapering off as more pedal pressure is applied. This leaves you with little ***ist where you really need it the most. The dual diaphragm booster tends to be a bit more progressive so you may be happy with it. If I'm not mistaken, these boosters were patterned after real OEM equipment. Mustang II and Chevette power boosters were the models. It may be worth it to you to convert your system to utilize one of these. Your pedal effort would be improved plus you would more than likely be supporting a US based remanufacturer. edit: sorry, just realized you're not in the US.
X38 the diaphrams seem to have let go, I have now been told the diaphrams are glued in not clamped .Not good. ELPOLACKO . thanks for the input the only oem. booster similar to mine is a GM holden gemini single diaphram,we dont have the choices you have in the states. Regards Good Captain.
good captain I think there are plenty of choices, you just have to go to a wrecker and invest the time to look. The Ford dual diaphram is good, but it's an 8". Many Jap cars have smallish dual diaphram boosters, maybe a Skyline? Don't discount pickups and vans either. BTW the Gemini was sold in the US as a Buick something or other. Part of the GM/Isuzu hook-up which goes on to this day. Gluing in seems a pretty ****py way to do something. I'm going to check that out!
Thanks X38 I will check out our local wrecker but my choices down here will be limited .I may have to go to the big smoke.
good captain I was told today that there are a couple of manufacturers in China. One is ok. Apparently Hoopers Stoppers or (someone else in Vic?) bought in a lot of them only to find they got the bad ones. It seems part of the problem is that all the rubber, including the diaphrams, is not proper rubber. There have been a number of failures, so you're not alone. The bad part is I don't know the specifics of which generic Chinese booster it is.
what MC can you put on the Chevette or Mustang 2 's 7" Booster? or do you / should you use the one that comes with it? what bore size are they?
Ford boosters seem to have a standard master cylinder mounting. You can swap them up really easy, just check the pushrod depth when you do so. GM stuff is almost as easy. I believe the "Corvette" master is a dead bolt on to the Chevette booster.
thanks..good info. my A has the push rod already on the brake pedal ***y. its internally threaded ..must be to fit up to the rod in the booster?
Yes, the pushrod inside the booster. There are a few different length aftermarket booster pushrods, inside rod. And companies like CPP have started shipping all of their master cylinders with the deeper bore in the primary master cylinder piston for boosters with a long pushrod and including a spacer plug to insert into the primary piston to take up space for the boosters with the short pushrod.
I bought a dual 7" for my Lincoln, it lasted about 1 hour.... So I replaced it with a dual 8", (because the 7" fit better than I thought it would), it has been working for a couple of months now. On the second attempt I tries to find a better one, tried for "American made", well I got one out of two, I got a "better" one from Taiwan....
Thanks El Polacko.. now to find a 7" DD booster that aint a POS!..seems like thats the hard part. a few places ive checked said OOS (out of stock) or more like STBY(****s to be you) maybe all these ****ed up boosters have been returned to the junk *** rebuilder and now theres no good ones out there to be purchased until the rebuilder gets its act together..any thoughts on that? Better yet..where can i buy a USA built Booster and MC that I wont be wasting my hard earned money on just to pay the second round of shipping to send the pile of **** back!? its one thing to pay X$..to get something you ordered..its a whole nother ball game when you have to pay another fee to send the pile of **** back
After buying an 8" dual diaphragm booster from MPB and having problems I used a junkyard booster out of a Astro Van. Works like a champ and was a whole lot cheaper. A friend had the same problems with his MPB booster and did the same as I did with excellent results also. Yes you're right I'm NOT a fan of MPB
Just a quick quip. I had a conversation with an aftermarket brake parts supplier one time, he was trying to convince me to stop using re-manufactured OEM parts on my brake kits and start using his. We talked about returns due to failure, he quoted me about one in 20 would come back stating eclusions in the castings, machining flaws or cut pressure cups from installation etc. I quoted him that maybe 1 in 50 of the units I sold would come back and less than half of those were due to improper bench bleeding. He was shocked to say the least. I have noticed the quality of these parts improving since then, but they are still a long way to go to be on par with new OEM suppliers like Raybestos and Bendix.
not a good track record for a safety device is it?..brakes are kinda important..there should be no acceptable failed parts percentage when it comes to the binders!..JM2 C Next time he comes in trying to sell you his **** ..ask him if he wants a ride in it, after you get done installing his **** parts
Even worse, think about all the master cylinders and booster that have been sold and still not used! I've been in this business, retail hot rod parts, since 1986. I would estimate that more than half of what was sold was never installed or put into use. I see it very often and get calls from customers that bought product from me nearly a decade ago needing instructions so they can finally use it! I will give them this, if you have a bad cylinder chances are if you can't get it to work you wouldn't drive it. And if you can make it work, it should work for quite some time. This stuff is pretty simple in it's manufacturing and function.
This subject has turned into a bigger can of worms than I thought. Any feedback about CPP quality/durability? As Von Rigg Fink says, these parts are pretty fundamental.
Good luck on finding a US made booster or master cylinder anymore. All the OEM suppliers I'm familiar with use parts from Mexico or China. And I'd be shocked to find an aftermarket part that wasn't made in China.
Been a CPP dealer for nearly 10 years now. Their quality has improved and the parts are pretty good. Just a bit lacking in the tech department is all. I have used three of the "all in one" master cylinders now. A bit big but not much more than the "Corvette" style master cylinders that are common. Function wise they are pretty damn nice.
Well when i posted this i thought i might not get much response , now i see others are getting the same problems as me with over priced ****. i wont even start about electronic distributors , my work-shop is slowly filling with junk. i,m sticking to oem whenever i can now.
