Why can't my Expy stop like a Chevy?? Booster issue?

[Miekk]

My boss has two new Chevy pickups and when I drive either of them, they stop with so much more booster power than my expy....

Is the expy designed to stop OK with the first pedal push, then when you pump it, like my dads old 78 half ton ford, the second time to set the pedal up and stop much better? Any immediate subsequent pedal pushes are all the same and significantly better than the initial push. When pulling our ATVs on the trailer, it's second nature now just to double pump them right a way.

I've only driven one other expy and it did the same as mine.

Are there changes I can make to the booster to boost more?

I only wish the pedal was responsive and positive as my bosses Chevys.

Thanks.

What model are the chevys, 1500 2500 3500?

Really? 2014 1500s


Just drove mother-in-laws 13 Equinox, another vehicle that will send you through the windshield just touching the brakes.


Been reading up. Plan on adjusting the booster plunger rod behind the MC a little so it sets up faster.

Because your vehicle is still running! Sorry, had 2 Suburbans and neither one made it past 72K miles. My 13 Expy, knocking on wood, is at 70K now with no mechanical issues other than warping rotors.

over adjusting will cause brake drag

Im sorry that youre having brake issues. Mine stops on a dime and much better then my step sisters 2012 tahoe and extremely better then my buddies 2004 z71 tahoe....and my brakes are on their way out.

There must be something wrong with your system, maybe a master cylinder internal leak or some other issue qith the system. Last time I had a hydraulic system that felt sponyy it ended up needing a master and slave cylinder replaced. Granted it was a clutch but essentially a similar working system.

Really? Yeah it really matters since GM trucks have 3 different brake systems.

You have a 2008, so have you owned it the whole time? When was the last time the brakes were flushed? What about the hoses? A lot of variables have occurred since it rolled off the show room in 2008 vs their 2014 and 2013s.

That is a good point, rubber lines over time degrade the pedal feel and effort. Find some steel reinforced replacements and that will help pedal feel and braking effort.

Their braking systems are irrelevant to my question... Why when I pump the pedal, the second push is nearing only as good as other vehicles first push?

Owned it for 2 years... done nothing and nothing has changed... Was accepting this until I drove these other vehicles that have far superior braking to this Expy.

We also have an 07 1500 here and it's better too. I'm beginning to think Fords are just not boosted to the level GMs are. My Mustang sucks compared to the Camaros, so maybe it's just a Ford thing. There's certainly plenty of other things I'd like to beat Ford for that are obviously so inferior to others!

I need to go out and drive some other expeditions to determine more..

I'm sorry to read that. You should sell your Ford and go buy a Chevy. Then you can always have a new one. Seeing as they need to be replaced every 70k miles or so. Its like changing your oil.

I won’t own a Guberment Motors vehicle
We Like the look
We love the ride and the IRS

Might want to delete that before you make a fool of yourself, you own a ford RIGHT?

Every forum has it's share a Jackwagons.....

What did I say, that I don't want to own a GM or that Fords have more than their share of issues? Comprehend much?

If if you're referring to the bailouts and you're a liberal who thinks we did an awesome thing, any more replies to your posts would be futile..

Yes it does and you are one for sure. lol...still think GM was the only bail out? Might want to read big boy. Anyway hope your brakes don't go out on you. That wouldn't be too good huh?

Back to the brakes, why haven't you serviced them correctly if you say you have owned the truck for two year?

I'm surprised no one caught the comment about pumping the pedal twice. That is usually indicative of a worn master cylinder - which lowers the performance of the braking system. Leaking seals will lower the pressure applied to the caliper pistons.

For a fair comparison you need to consider the weight of each vehicle, tire size, brake size and diameter of the rotor, what material the pads are, size of the master cylinder bore and stroke, caliper piston size, etc.
You can get very aggressive pad material that will eat the snot out of a rotor - and put you face first into the windshield.

It could be you are comparing a worn system to a fairly new system that doesn't have the same amount of wear, the chevy may have a "larger" master cylinder than the Ford, it may be ceramic pads to semi metallic, etc. Without looking at the specs between the two it would be hard to pinpoint the difference.

As far as the rod goes, you need a slight amount of play in the pedal. I don't what the specs call for but I wouldn't have it less than 1/4 inch unless the factory calls for less. If the pedal is harder to push than normal it may be from a leaking booster. If the leak is bad enough there may be a reduction in the assist.

ur comparing pickups to expedition suv? lol

It was the first thing I said....i had my clutch system (hydraulic like a brake system) have the same issue and master and slave cylinders needed replacement. Once they were done the pedal was perfect from there.

New fluid is no different. Ford says all is normal.
I've researched a lot of forums and everybody that has soft brake issues, and has replaced nearly everything, finally ends up shimming or adjusting the booster rod out so it sets up much faster. All seem to be happy with that fix.
I took the master off and my booster does not have an adjustable rod so not sure where to go from here yet.

My 2011 EL takes a bit to stop despite the braking system being in good shape, but the vehicle is 6,000 lbs. I previously owned a '96 Probe GT, '92 Explorer, '98 Crown Vic, and '00 Mercury Mountaineer; no complaints about brakes on any of them.

Because your vehicle is still running! Sorry, had 2 Suburbans and neither one made it past 72K miles. My 13 Expy, knocking on wood, is at 70K now with no mechanical issues other than warping rotors.

Sweet jesus. Why did you buy the second one? If any of my vehicles get less than 200K I'm never buying that model again.

 

[01yellerCobra]

New fluid won't fix a leaking seal. The fact that you have to pump it shows it's not normal. Ford probably doesn't know what's normal so they're guessing.

My 08 stopped just fine. Even with 24" rims. And I was never concerned about stopping with my boat behind me. Something is wrong with your system.
