Over the weekend I made use of the wet weather and tried some helis in my wrx…..all on private property
After a 360 I stopped accelerating, put my clutch in and put my foot on the brake to stop me rolling into a fence.
And my brake peddle wouldn’t budge! So I hit the fence …..i was only moving slow, but it felt solid!
Only a few scrapes and scratches, so no real harm done. Thanks God!
So thinking about it now, when I went to push the peddle it felt further out than usual, and about 2 or 3 seconds after I hit it slowly went soft again, and I could brake normally.
I'm thinking it would be something to do with the brake booster, and the boost from the engine giving it pressure not vacuum…
Does the brake booster work from the engine pressure, or is there a vacuum pump?
does this often happen? what fails causing it?
cheers in advance, Steve.
