Our Hydropower hydraulic brake assist power booster fits 1947-53 Chevy and GMC trucks and generates up to 1800psi of line pressure to the brake calipers. It is fitted with a POL master cylinder and proportioning valve. This kit is powered by hydraulic line pressure from the power steering pump. Firewall and valve cover clearance is equivalent to a 7" diameter vacuum booster. The firewall brackets are correct for 47-53 1st series GM truck applications.The average power steering pump puts out from 800psi to 1400psi line pressure. The Hydropower uses this to convert to pressure to apply against the master cylinder. This greatly improves stopping performance and driver feedback. These hydraulic power boosters can be easily installed on an existing vacuum booster vehicle or used to convert a manual brake setup to power with ordinary hand tools and average mechanical ability.

Easy to use Simple & easy to use.

Would have given 5 stars except the date font was too small. Great price for a basic watch that gets the job done

THIS WATCH IS NOT WATERPROOF AT 8 FT
Color: Black/Black/ Black Digital
DO NOT BUY TIMEX WATCHES - TIMEX ARE LIARS- I just called Timex and was told "a 30 meter rating is only for washing hands, not for swimming" This is a BIG FAT LIE. If the watch is only for swimming then SAY THAT! I AM VERY DISATISFIED- THIS WATCH LEAKED IN 8 FT OF WATER WHILE SWIMMING IN MY POOL . -ALSO, WATCH FACE IS VERY DARK AND HARD TO READ. Even if it didn't leak I would be very unhappy. I want a refund? This watch is only a week old when it failed. DO NOT BUY TIMEX WATCHES

Great!
Color: Black/Black/ Wjite Digital, Color: Black/Black/ Wjite Digital
Great, Just as I remembered them! The only difference is, a shorter band. I thought I had small wrists for a man, but with this band I have to use the last hole to be comfortable . I may add one more hole to the band!
