starletgt-shady Posted June 29, 2013 Share Posted June 29, 2013 Hey guys my brake peddle is rock solid I took the vacuum off from the inlet manifold to the brake servo ( I think, big black round thing) to change it to suit uprated manifold. Air came out under pressure when I took it of. Is this my problem with the brakes?Any help be great thanks. Quote Link to post Share on other sites
AdamB Posted June 29, 2013 Share Posted June 29, 2013 Yep certainly will be unless you put it back on the manifold? I'm sure aftermarket inlets have a fitting for the servo? Quote Link to post Share on other sites
starletgt-shady Posted June 29, 2013 Author Share Posted June 29, 2013 Yeh it all back together. Took the fitting of the standard inlet and put it on the new one. Only disconnected it to put a longer hose on. Quote Link to post Share on other sites
starletgt-shady Posted June 29, 2013 Author Share Posted June 29, 2013 Does the system need to be bleed again? Quote Link to post Share on other sites
Keri-WMS Posted June 29, 2013 Share Posted June 29, 2013 You shouldn't need to if all you did was take the servo/vaccum hose off then replace it. :-) Quote Link to post Share on other sites
starletgt-shady Posted June 29, 2013 Author Share Posted June 29, 2013 Yeh just took it of and replaced it. I am using wms 4 pots. When I took the vacuum line off pressure came out. Quote Link to post Share on other sites
Keri-WMS Posted June 29, 2013 Share Posted June 29, 2013 Same thing happens if you pump the pedal a load with the engine off - the pedal goes hard as the vaccum is lost. Start the engine and it puts the vaccum assist back, and the pedal goes soft again! Quote Link to post Share on other sites
starletgt-shady Posted June 29, 2013 Author Share Posted June 29, 2013 Yeh that's what I thought. When it's running it doesn't get any softer. Can you bleed the servo? Quote Link to post Share on other sites
Keri-WMS Posted June 29, 2013 Share Posted June 29, 2013 There's nothing to bleed in a servo itself. Have you got the hose back on it? Also most servo vaccume hoses have a one way valve in them that you'll need (if the OEM one had it). Quote Link to post Share on other sites
starletgt-shady Posted June 29, 2013 Author Share Posted June 29, 2013 Yes the hose is back on with the one way valve on. I'm pretty sure I put it on the same way I took it of but could put the valve in the other way see if that helps. Quote Link to post Share on other sites
