#171 of 179 Check Brake System Alert by Chuckles37

Sep 17, 2012 (1:51 pm)

FEH 09, 44K miles. Wife driving, red brake light, chimes and check brake system comes on, brake petal to the floor, gets the FEH to stop. Luckily she is going slow in an isolated area. Calls me, I start it up, no alert or alarms. Drive slowly and carefully the 6 miles to Ford dealer, no issues on the drive. Has a code about the brake pressure sensor. Tech finds the wiring run to the connection is very tight and the connector is not fully engaged. Reroutes wiring run to get some slack, tightens everything up, code is gone, drives fine. Based on some other estimates in this forum for repair parts, the $100 fix for this problem, instead of $4K computer, was a lot easier to pay. Glad something was found.

I've got a 2009 Escape Hybrid with 76K miles on it. I've experienced braking problems when traveling down very steep grades (i.e. Mt. Whitney portal to valley, etc..., 10+% downgrades). Specifically, the vehicle shakes severely and the regenerative power/battery meter doesn't indicate that it's being regenerated, as it normally does when the brakes are applied. This happened the summer of 2011, than again this past summer, each time only once, while traveling down severe grades. I had the transmission in low to help keep my speed down to minimize the braking. The shaking would typically occur while braking at 40-50 mph +/-. This has not happened in any other situations, and the brakes appear to be working well at all other times. Any thoughts?

"....transmission in "low"...."
 
"B" mode also?

I don't know about "severe" shaking, but if you are in "L" going down hill, the battery will max out at about 66% SOC. After that point, the FEH will use the engine to brake, which can be pretty loud. Next time, shift back to "D" and see if the shaking goes away. But on my 2008, the only thing that happens is I hear the engine. If there is shaking, something may be wrong under the hood.

Might be the EBD, Electronic Braking Distrbution. The system tries to "balance" braking front vs rear. I most notice it activating on a slight downhill with wet roadbed, feels like cross multiple railroad tracks.

Really? Since you never owned an FEH, how do you know what Ford EBD feels like?
 
As an owner, I can say that I have never had any such feeling from my 2008 FEH.
 
I normally make sure to ignore wwest when he trolls other forums for vehicles he has never owned. But I had to clear up misinformation.

"..how do you know what Ford EBD feels like?..."
 
Never said I did, "might be" is in no way a definitive team.
 
And why would you assume, suppose, that Ford's implementation of EBD would differ significantly than others?
 
On the other hand since the FEH must "contend" with three separate braking modes (front ONLY [regen], combined [regen front, frictional front/rear], and frictional only) I would suspect that activation of EBD might even more pronounced, noticeable vs my RX300.

Like I said, I don't answer trolls.
