Brake pedal, tick over???

when I'm slowing down my revs go up. Change down into 3rd for corners and roundabouts. 4,000rpm.

Car slows, then back onto the throttle.

Where does this tick over bit come in?

[calgon]

i was stopped in my garage at the time with the engine running at tickover, i started to pump the brake pedal and i started to hear the tickover go crazy like it was about to splutter and die.

Could be something to do with the servo leaking

As usual, it takes someone with a brain cell to answer the question...

What are brakes on a Yaris? A Hydraulic system.

Where does a hydraulic system get it's power? The engine.

Am I going too fast?

When the engine is sat idle, it's using as little fuel and therefore power, as possible. When you start pumping the brakes, or turning the steering wheel (on Ph1 models that is... Ph2 and Mk2 have crappy electric steering) or you turn the A/C on, or anything else connected to the auxilliary drive belt, it uses some of that tiny bit of power, and therefore the revs drop and guess what? That's it, you're with me now, when you lift off, or stop turning, or turn the A/C off, the revs rise again. Gee, it's tough going this.

Eeerrrr forgive me for being a little slow, But....

When he says " i was just pumping my brake pedal "

Is not the SERVO unit operated by vacuum.

The vacuum pick up pipe is on the Inlet side of the manifold.

So Pumping the brakes will rob the manifold of air, causing the Engine to Hunt.

This causes the revs to go up and down....

Switch off the Engine and Pump the pedal several times and you run out of Vacuum...pedal goes hard.

Keep your foot on the brake pedal, start engine and the pedal will fall a little. This is NORMAL.

Sorry that you feel that way..................I feel that you may just not be used to Seveer's sense of humour and irony....................stick with us, you will get used to him :group-cuddles:

He is just a simple Yorkshire Giant ;) with a heart of gold

Or... Iv got a sense of humour. FFS there's some ninny's in this world. I gave you spot on advice, where can the complaint be? And I didn't have a clue about this '1.5 trend' malarkey, so it's not related to that either. Some people need to learn some key skills if they're to survive in this world... Number one; get a life.

This club does encourage new members, that's the damned problem... just like our beloved government... protect the new, out with the established. Pander to the needs of the few... etc etc. What's wrong with sound advice? What's wrong with sarcasm? Nothing. Get a life folks, it's the only one you've got to survive with.

And Ryan... Don't patronise me. It's quite rude.
