Description

GM Genuine Parts Power Brake Boosters are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These boosters connect the brake pedal apply system to the master cylinder. The brake booster is a force multiplier that causes additional force to be applied to the master cylinder for additional braking power. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

    • Fits a Chevy P30 Motorhome / Workhorse P32

I was able to fit the ACDelco 178-1036 in my Class A Motorhome. It's an almost bolt in replacement. There are two differences: 1. The push rod hole is about 1mm 1/16 too larger then the bolt on the P30 - I've just wrapped a few layers of metal flashing around the bolt to make it a flush sit. Basically building a sleeve for the bolt. 2. The rod is slightly shorter. Which means that the brake pedal sits a tad lower - (adjusting the brake light switch - disconnect the cables and screw it inwards) -when you install the whole bracket assembly make sure to have it all the way down in the screw holes. Otherwise - on my 2003 Workhorse not even the push rod for the brake master cylinder needs to be changed out - has the same exact length. The first test drive around the block was a great success - the brakes feel much better, less pedal pressure - stuff was flying forward :P This booster has about 1/4 inch more piston diameter. Such it has more support. What the P30/P32 platform definitely needs. Further there are no new parts available for those old RVs anymore. This new original part is a easy, almost bolt in replacement and upgrade. ... show more

    • Great fit and good pedal feel
I installed this on my 03 sierra 2500HD. It fit perfect and the brakes feel so much more responsive than before. Like others have said, you may have to open up the hole on the shift that connects to the brake pedal. At first I did not but did in the end as I was trying to trouble shoot why my truck wouldn't come out of Park after everything was installed. Turns out I had damaged the brake switch when I was removing the 4 nuts under the dash. Be very careful with this switch and remove it fully so it does not get knocked around. Very happy with this product and would have been an easy install if I hadn't damaged the switch. Much cheaper than the direct replacement one too. ... show more

    • Your brake light switch may not work unless you drill out the rod!
Took a long shot on this for my H2, which is not listed as a vehicle this works with. After installing the unit I spent hours head scratching and troubleshooting why my shift interlock and brake lights didn’t work—let me save you trying to solve that mystery. There’s a few reviews and several write ups about some people having to drill out the under dash rod from the new hydroboost that connects to the brake pedal. But they never explained why and I thought it had to do with the pin on the brake pedal being slightly too large for the rod to hydroboost to connect properly. Turns out you may have to drill the new HB rod about 1mm or so larger (not very much at all) in order for your brake light switch and shift interlock to work properly. I used a step bit from harbor freight and drilled out both sides of that rod by one step on the bit, like I said, not much needed. It’s really that simple. And it turns out this hydroboost unit is actually a great upgrade for better performance on your 2001-2010 GM heavy duty. This is a redesigned for 2011 unit with better performance overall. ... show more

    • Works on previous gen trucks
Bought this to replace the leaking one on my 05 duramax. I have found this one improved the trucks breaking and turning. Breaks faster with less pedal. Steering is a little more positive as well. I would consider this as an upgrade for previous gen trucks.

    • Great improvement
Fit perfectly in my 04.5 LLY. Brakes are noticeably better. Still a chevy brake pedal but worth the money.

    • Works on a 2004
Got a 2004 2500HD and it’s a direct replacement. Bolted right in. Quick job. It has a lot more force. It will stop you.

    • 2007 gmc duramax 2500 upgrade
Upgrading your Hydrobooster from my 2007 classic gmc.. on the rod hole you need to slightly drill out the hole from 5/8 to 41/64 diameter drill bit will work just perfect;)
