brake pressure gauge...usage?
After a year or so of honey-do's, I'm back.
Things are running but now I gotta get things stopped!!! I'm getting a hard pedal but very little pressure. Am I using the brake pressure gauge correctly? Any secrets? Want to make sure I'm using this gauge correctly before I invest in smaller master cylinders.(Any for SALE?) I have a Wilwood dual floor mount with 3/4" front and 1" rear cylinders. Only getting 500 - 600 pressure at wheel cylinders. Thanks Dave |
100 lbs at pedal x 5:1 pedal ratio, divided by two (force split between the two cylinders) divided by the area of the master cylinder (1" > .78 sq in.)= 340 psi.
So, you're pressing pretty hard. |
Yeah wasn't sure of the recommended pressure. Haven't driven car out the door yet. Just checking things
before the GRAND moment. |
What I don't understand is that wilwood said.......quote.....
"With a 5/8 bore master you should see about 1935 psi and with the 3/4" bore, your psi will be about 1364 psi. This is based on the information you provided for your 6:1 pedal ratio." So.... people are saying 300-4000psi at the wheel cylinder is fine but wilwood is saying over a 1000 psi is a good reading. The instructions with the gauge I'm using says don't drive a car with less than 900 psi. I'm lost. I do have a 5/8" front and a 3/4" rear MC setup planned. Dave |
See my analysis over on the other thread.
