Report: Power Brake Units May Leak Fluid From Hydro-Boost Unit
Chevrolet Suburban 2500 Problem
Average Mileage: 161,980 mi (50,000 mi - 265,600 mi)
Power brake systems using "hydro-boost" may leak power steering fluid from the hydro-boost unit located behind the brake master cylinder. Replacement of the hydro-boost unit is the common repair to correct this concern.

Power Boost Brakes and power steering fluid leak, I had the leak start awhile back, cant afford to pay to fix it, so I used the Oil Resistant Gasket sealer, with extremely great results!!!! I applied the gasket sealer around the seam between the master cylindar and the power boost component, no leaking at all.

power steering fluid leaking from hydra boost housing. What is the reapir?
for the 4th time since I boght this new, I have this leak. Before I always had it repaired...is this soemthing that I can do myself, I have done ALOT of car repairs...not just changing a tire, just never tried this...is the system pressurized or is it basically take off the old, install new power steering fluid, and bleed brakes???
I have a GMC 2500 Suburban....I have replaced the Hydro-Boost SEVERAL times...
The suburban has a hard time stopping when it gets hot. The steering locks up and the
suburban does not want to stop.
I have called GMC company to see if they have had a recall...since I have replaced it several times. They said no. I told them the problem and they said they don't know what to tell me. OBVIOUSLY...it is a problem with many suburbans. You would think they would get this fixed.
I would like to know how I can get this exchaged from a Hydro-break booster to a vacuum break booster since this is not working. This is rediculious and it has become to the point of being VERY EXPENSIVE AND VERY DANGEROUS. I am mechanically inclined and would like to do it myself.
I don't want to get rid of my suburban I love it....it is the break system that sucks. If anyone knows how to please let me know.

Sameproblem, I have replaced this with the dealer 4 times. This last time could not afford the almost $1200 they wanted, went up $500 in 4 years... anyway, went to Autozone, got new one, a few hours, cramped quarters under dash for the 4 mounting bolts, but it went on very smoothly, bled ABS with no problems and everything is great, under $200.00 at autozone. While I awas trying to decide how to fix (dealer or myself) I was using the black oil resistant gasket material around the entire seam between master cylindar and booster, only had to rea ppy twice in several months- it worked really well and got me to the time that I had the monies to fix.
leaking power steering fluid around brake booster. Ended up replacing brake booster and master cylinder (since they were both original). The brakes were always soft, but after replacing booster and cylinder they seemed even worse. I took it back to shop and had them bleed the ABS. This is difficult to do and you need a special tool to cycle the ABS, but it worked great! Brakes are better than ever now, and I am not afraid to trailer horses anymore!! See this article for more detals on bleeding the brakes. http://www.gmtruckclub.com/forum/showthread.php/19182-Bleeding-ABS-brakes-w-o-Tech-1-Scan-Tool
