I push on the brakes and idle goes up ?
I just got stainless lines and new brakes on my car . They were bled properly and are doing still what they were originally doing . When I push my brake pedal down my idle increases?.. what would cause this? Also, the pedal takes longer to push down and is almost squshy .
Vaccum leak ?
Brake booster?
Master Cylinder?

i heard the stainless lines can cause the differnce in peddle feel you are feeling.
Mine does this every now and again and i have never noticed a vaccum leak,
you can always test but pulling off your intake tube and while the cars runing hold your hands over the tb make sure there is no gaps. if the engine keeps runing there is a leak if it dies there is not.

when you push the pedal down to stop, Its a longer push to stop. Under high speeds the pedal will vibrate rapidly. Also when you step on the brake pedal at idle you can see the idle increase.

yeah idle increase is normal, its called vaccum. the pedal vibration is caused most likloy by bad rotors. buy some oem honda ones dont get aftermarket bs they suck *****.
mushy felling could be air in the system. bleed the brakes properly(all 4 wheels in the right order)

You have air in your lines.

the rpms would increase on my car when i was sitting still and pumped the brakes, its just revving the motor to create more vacuum for the braking system, but the mushy pedal, bleed those bastards, get a power bleeder or something, make your life easier

Re: I push on the brakes and idle goes up ?
I thought RPMs increase when you press brakes because it uses some engine power to use the power brakes (hydraulic). When I'm sitting at a light, and I push pretty hard (not abusively) on the brakes, my RPMs raise about 4-500 RPMs. From like 7-800 RPMs to about 12-1300 RPMs. If this is not supposed to happen then I have a problem too! But as far as I've heard, just like with some power steering setups, it raises your idle a little.

It uses no engine power to use your brakes and they are not power assisted. Your brakes are vacuum assisted, hence the brake booster. Which is why engine idle will fluctuate when you use your brakes while no load is on the engine, vacuum is changing and causes the engine speed to fluctuate because of an increase/decrease in vacuum

Can you make what the "check valve" more clearly?
And where its located?
Cuz mine does same and I wanna replace the check valve

Re: I push on the brakes and idle goes up ?
Check valve is a one-way valve in the vacuum line running from the intake manifold to the brake booster. It prevents vacuum from being forced back when you push the pedal. If its bad it will let back prrssure out and the pedal will feel squishy

if you want to find a leak, get some tb cleaner and spray on the areas where leak could be a problem. watch out tho, its not the safest of things to do cause it combustible, but when you find the leak the engine should sputter b/c of the cleaner.
