joe588 Posted March 31, 2011 Report Share Posted March 31, 2011 As above, I just noticed this today. I think it probably is normal, but I thought I better check! When idling if I press the brake pedal a few times then the revs rise to about 1400 from 800 and then drop back down. Is this normal or do I have an air leak or something? Cheers!

sbdags Posted March 31, 2011 Report Share Posted March 31, 2011 No it's not. My revs might go up 100 when pushing the brakes but you shouldn't be seeing 1400 revs. I don't even get that high when I have the air con on. Link to comment Share on other sites More sharing options...
rpsmith79 Posted March 31, 2011 Report Share Posted March 31, 2011 Possible air leak from the brake booster maybe Link to comment Share on other sites More sharing options...
joe588 Posted March 31, 2011 Author Report Share Posted March 31, 2011 Ahh, problem to fix. What do you think it could be? Leak in brake booster line or something? or brake cylinders themselves? Possible air leak from the brake booster maybe Snap! Yeah, think I'll try this tomorrow. If I spray WD40 allover everything, the revs should rise if there's a leak?

rpsmith79 Posted March 31, 2011 Report Share Posted March 31, 2011 Well the brake booster is the only thing on the braking system that is in any way connected to the engine, so that would be the first place i would start checking Link to comment Share on other sites More sharing options...
princy Posted March 31, 2011 Report Share Posted March 31, 2011 Does sound like a leaky servo Link to comment Share on other sites More sharing options...
joe588 Posted April 1, 2011 Author Report Share Posted April 1, 2011 (edited) Also, I've done 215 miles on a tank of fuel, somethings up here. Not driving like a willy either! Video of the problem. Doesn't rise as high as last night but the engine wasn't as hot Edited April 1, 2011 by joe588 Link to comment Share on other sites More sharing options...
yellowchinaman Posted April 1, 2011 Report Share Posted April 1, 2011 If it was during warm up then it's normal Link to comment Share on other sites More sharing options...
