Gareth Dickens Posted January 28, 2008 Share Posted January 28, 2008 Anyone know what range it is? Where can I find out? Quote Link to comment Share on other sites More sharing options...

Gareth Dickens Posted January 28, 2008 Author Share Posted January 28, 2008 Not really sure what you mean......? I need to know the max pressure in the brake system during braking. Say 250 lbs on the pedal pushing 1sq inch piston equals 250 psi system pressure. Does anyone have more accurate info? Quote Link to comment Share on other sites More sharing options...
rtbarton Posted January 28, 2008 Share Posted January 28, 2008 I need to know the max pressure in the brake system during braking. Say 250 lbs on the pedal pushing 1sq inch piston equals 250 psi system pressure. Does anyone have more accurate info? Don't forget to take into account the leverage of the pedal. E.g. if the pedal is 12 ins long and the pushrod is 2 ins from the pivot, the force on the piston is 1500 lbs for 250 lbs at the pedal. (Assuming the pedal is a straight bar and the forces are at right angles to it) Quote Link to comment Share on other sites More sharing options...
tacr2man Posted January 28, 2008 Share Posted January 28, 2008 You dont say if it is servo assisted, I cant think what you would need to know this for, unless you are going to convert to a hi pressure hydraulic system ala citroen/rolls royce Quote Link to comment Share on other sites More sharing options...

Was hoping someone would know the actual value.I want to fit a brake pressure gauge and need to know the operating pressure. Quote Link to comment Share on other sites More sharing options...

Not being funny but a lot would depend on how urgently you needed to stop, and if you were prop forward for Wigan The hydraulic hoses would be the limiting factor you might try a hydraulic hose supplier they would probably be able to tell you if you showed them a brake hose from a landy HTSH Quote Link to comment Share on other sites More sharing options...
rtbarton Posted January 29, 2008 Share Posted January 29, 2008 Google "Brake pressure" - loads of info. Brake Pressure Tester Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted January 29, 2008 Share Posted January 29, 2008 Most brake pipes and bits are rated to 3000psi from memory, although that's including a safety factor. I don't think you get above 1000psi (probably a lot lower) during normal driving unless you really stamp on it. Why do you want a pressure gauge on your brake lines?

With my new gearbox and xfer case I lose my handbrake. I want to fit a ball valve and press gauge so I can press the brakes and then trap the press, giving me parking brakes. The gauge is to monitor that it hasn't lost press. Quote Link to comment Share on other sites More sharing options...

I'd check the legallity before throwing money at it. Quote Link to comment Share on other sites More sharing options...
