Thumbs up Just added Hydroboost - Incredible

Two weeks ago, as I bled brakes after 2 year frame off resto, and still felt crappy brakes, I decided to go for hydroboost kit.....spending all that money to make a car go fast and look good, felt it important to be able to stop. Just road tested it today. Talk about incredible pedal response and stopping......one of the best Chevelle investments ever for me.....went with CPP unit with Chrome M/C and stainless lines. Was able to keep my Wilwood discs, rear drums, same brake lines, and prop valve. If you are contemplating HB, do it.... you won't believe how fantastic. was very easy install and looks good to me too. before and after pics below. anyone interested in slightly used Wilwood M/C, booster, and vacuum canister? can't get that one pic to upload correctly...sorry

Re: Just added Hyrdoboost - Incredible

agreed! Hb is the best upgrade I have done to mine so far, with the exception of needing to upgrade my fillings. These things under emergency conditions will bring the Beast down and quick! Like an anchor tossed out behind the car!

Ahh the fillings.. maybe I will wait till I have dentures and see the teeth mounted on the inside of the windshield!

Did you get the back brakes adjusted properly? Did you just open the valve on the port until they locked up? The CPP instructions aren't too clear on the adjustment procedure.

Re: Just added Hyrdoboost - Incredible

Cool, I have the same set up. I didn't have too good of luck with some of CPP's other stuff so I was a little worried about the hydro boost. This makes me feel a lot better.

Re: Just added Hyrdoboost - Incredible

Rod, how does that 59" rear axle work in your 66? That's like an inch narrower that the stock axle, right?

Re: Just added Hyrdoboost - Incredible

I had one of the Hydratech units on my 72 Camaro and agree they provide amazing brakes. It is certainly on my "to do"list for my 70. Great stopping power and also think they look great under the hood.

Re: Just added Hyrdoboost - Incredible

Larry, are the tires close to the frame or inner fenderwell?

Re: Just added Hyrdoboost - Incredible

Love my Hydroboost. Definitely recommend the 1 1/8" bore master cylinders over the 1" and I've tried both. Nice and firm pedal.

It's really nice, I couldn't get the wheels in an off set to work with the stock width, and I was going to upgrade the rearend anyway, so, I just had them narrow my new 9" to 59" when I bought it. It didn't cost anymore than a 60" one so it worked out well. Got it from Quick Performance in Iowa, super guy and super to work with. I also got my drive shaft from him as well. The best part about it is that he is significantly cheaper than the usual suspects.

My wheels are Ridler 695's and originally thought that I'd buy them to mock up the car with but once here I really liked them. Kind of reminds you of the 80's with the Cragers yet a bit of a modern look. I like the soft lip and the fact that they chrome the wheel all of the way out the back, unlike others that usually stop once you get to the hub, at least the 'good' chrome. And, I bought 4 of them for the less than the price of one of those really fancy, light weight, forged offerings. I may not be as cool but I'm happy...

With a MT et street radial 275/60 the tyre is about 1/2" away from frame, maybe a little more haven't looked in a while ,

I have a different master cylinder, so yours may not be adjustable. Mine doesn't use a proportioning valve because it is built into the master cylinder. You can see it in my "Garage" in the "Under the Hood" section.

Re: Just added Hyrdoboost - Incredible

Roger that Mark. Thanks. That Prop valve is a pain..especially it being on the frame. Wish I had known you can move it close to the M/C or eliminate it entirely before I redid my brakes. will next time!!
