i'm leaking power steering fluid at the master cylinder. i looked around for a rebuild kit but found nothing. what vehicles are the replacements compatible with? i was going to check the local junkyard this weekend and look around before buying an aftermarket one. any brands to avoid? vehicle is a 2001 1500hd silverado 6.0

 

Personally I wouldn't take a chance with a used one. I just installed a new one on my 2500 Suburban and picked it up at O'reilly's. It's guaranteed! It's not a real hard job but not one I would want to do over and over because I got a bad used one.

 

it doesnt look like a really hard job to do. ill see what the local parts store offers, i have some coupons. thanks

 

No, the hardest part is getting to the fasteners under the dash.

 

hm, where are they located? is there a write up on how to do it? i looked at it on alldata and it was rather brief in the instructions and didnt say about any bolts under the dash

 

They are fairly easy to see and not that bad to get at with a swivel and extension. If you look at the HB unit you will see the 4 studs that go through the firewall - each one of those has a nut on it. Don't sweat it, it isn't that bad.

 

thanks. i took a look at one in a junkyard, of course it was leaking. i saw its fastened with inverted torx bolts, so it looks like ill finally have to get a set

 

I haven't seen on emounted with inverted torx. The studs that hold the hydroboost to the master cylinder have inverted torx on one side but you can use a regular socket/wrench on them.

 

I have the same issue with my 75 c30. Hate to buy a new one so I thought I'd try the kit. Got it off the truck with pretty good ease but a couple issues I need assistance on.
1. How do I remove the rod from the unit that connects to the brake peddle?
2. Which wrench should I use to remove the large nut holding the unit to the plate that holds it to the firewall.
3. Where could I find a good used unit from a 75 or 76 c30? I live near Memphis, Tn.

I will try to upload pics. of the unit.
Thanks
