I have a 06 RT that has a vibration under braking.
It has been at my local dealer for a week!! With no results....
Steering wheel rocks back in forth pretty violently under hard braking Or under normal braking. I have swapped a lot of parts from another Ridgeline with no changes in what it does..

We have replaced
Rotors
Calipers
Pads
Axles
Bled the brakes new brake fluid
Unplugged abs
Tried used wheels new wheels with tires
Bearings
Lower control arms new bushings
Aligned it
Different lug nuts
We are completely lost and looking for a new idea!

PLEASE HELP WITH ANY THOUGHTS

Thanks

Tie rods are good. One of the first things I checked and master checked after they replaced rotors. I haven't checked steering rack might be our next step?????

Despite all the parts replacement, the only thing that commonly causes that symptom is the brake rotors. Loose hubs won't cause shaking. At one point in time people would machine rotors before installation. Cheap rotors should not be trusted. I used EBC rotors on our RL for 75K miles w/o fault.
And have thousands of brake jobs under my belt. Because "it has been done" doesn't always mean it was done correctly. On the off chance tires are part of the equation, have them inspected and rebalanced.

I have had 4 sets of rotors and pads installed by 4 different mechanics because everyone has the same mentality as u. I'm not being rude it's just that every mechanic says that every other mechanic sucks.. I have 2 "Honda Master" mechanics on it now with at least 20 man hours in it searching for the problem...
I have installed new wheels and tires off a pilot and off a Ridgeline
Ridgeline had about 1000 miles on wheels and tires.
2 sets of oem rotors
1 set of power slots
1 set of delco
All have the exact feel and vibration
Steering wheel rocks side to side
U can barely read what station is playing on my monitor in the dash.

A friend had a similar issue. Long story short, the rubber brake hose going to the caliper was bad.
Just a thought and good luck.

Edit: Are the calipers warm or is one a lot hotter than the other?

Definitely a brake problem.... I agree that you probably have inappropriate hydraulic pressure being applied somewhere; which could be caused by line blockage.... but could also be caused by faulty brake system components (abs, etc.).
Is it your dealer who is trying to figure this out for you?

If they don't get you figured out, you might try a reputable independent brake specialist.

Your EBC brake rotors are made in one of a few Chinese factories just like all of the rest!

It's at Honda dealer now. It's been there for a week.
They have ran a pressure check and they claim it's ok. I asked the same thing thought there was blockage in a line or a kink in a line.
The vibration is always there cold hot 1 mile or 100 miles. Doesn't matter.
I have worked on race cars and work with several race teams here in Indianapolis and everyone is clueless because it feels just like warped rotors..
I will call the Honda dealer and have them check the rubber lines.


Thanks for the ideas

"PLEASE HELP WITH ANY THOUGHTS"

Okay, you armchair mechanics out there, brace yourself for this one....


I hate to say it but they are gonna have to run the vehicle on a frame lift and have somebody at each tire looking for what is causing the problem. I know that is a crazy idea but sometimes you just have to lift it off the ground and run it. (I'm not saying lift it 6 feet off the ground either)

Since there will be no weight of the vehicle to slow down and stop, all the vibrations and movements will be much smaller and it will obviously take no time at all to stop the wheels.

Also applying the brake lightly while also pressing the gas may give some indication to what's causing problems, either through suttle noises or movement.

I'm sure the Master Honda Techs have already done this though and it hasn't been mentioned, we did this in tech school to diagnose a noise on a Durango.... better than having somebody hang their body out of a window while you are driving in the lot lol (which also gets done).

I did see it mentioned anywhere but does it pull to either side when braking?

When you replaced the calipers, was the caliper mounting bracket also replaced (they sometimes come in a whole unit) or was it just the caliper itself?

Where did you get that notion from?..? :act060:

Folks, EBC is UK/English made. I received the first set of pads in the USA (rotors were just being released in '07-ish). EBC told me the backing plates were stamped in Canada, and friction material made and bonded in the UK. Rotors are made of Virgin Grey Cast iron. Not what one finds from Chinese imports, at, all.

With that said I will be terribly unhappy if it can be verified EBC is now manufacturing off UK soil in the orient or other sub-par cost cutting region.

I have used and installed EBC brakes since 2003 on many vehicles. Last set went on a G8 I upgraded (475WHP) last month (and other high power cars, even minivans). G8 customer is amazed compared to stock brakes even with only 26K miles. May have lost a BBK (big brake kit) sale, but customers always come first. Best brakes for the money, period. Can't tell you how many accidents we've avoided, even some of my customers with better than OE binders.

This is from EBC's website.

EBC manufacture the vast majority of its automotive rotors including Premium brake rotors in the UK or Europe. Outside these sources where castings or finished rotors have to be bought in to complement the range, the strictest quality controls are applied to ensure the safety and quality of the parts we sell. We source only highest quality parts from well known and proven OEM manufacturer vendors and we are responsible for and guarantee those parts to fit and perform as expected. All suppliers of castings for the EBC group are ISO approved to the highest specification and have been visited and approved by the German TUV authorities.


Basically it may be that EBC rotors that one can purchase for the Ridgeline are made in the UK or Italy. It also may be that they are Chinese made.

They are expensive, and in price similar to or more expensive that OEM rotors. Are they really better and worth the money? It would be interesting to know where the Ridge pieces are manufactured and if they really do have unique metalurgy. Your 2003 data is 10+ years old and things most certainly can change. Maybe it has and may be it hasn't.

Truck does not pull to the sides it just vibrates the hell out of the steering wheel

I'm assuming just caliper???

Appreciate the ideas.

They ordered new rubber brake lines today will be installed tomorrow..

I asked about the brackets because I've seen a truck with disks that had a seized guide pin that was hard to diagnose since it wasn't obvious. The pin wasn't sliding into the bracket but instead was locked at full extension.

I guess at this point you've replaced all the common issues and now you are left with random ones.

It is. The caliper mounts to the caliper bracket by way of the slide pins, and just "cups" the brake pads between the caliper's outer "fingers" and the pistons on the inboard side. The caliper bracket is what actually retains the brake pads, and is bolted to the steering knuckle with two fairly large bolts. The caliper bracket must be removed to pull the brake rotor off.

This is not a Ridgeline, but it shows the concept. The yellow arrows show where the caliper bracket bolts to the knuckle. The red arrows show where the caliper mounts to the bracket with the slide pins.

Very sorry to hear this. 20 man hours at the dealer plus all those parts means you must be nearly $4k into the job by now which is probably about 1/3 of what you paid for it. That sucks...

The dealership was beyond cool with me and didn't charge me a $1!!!
They felt really bad and said its the first time ever they have never been able to fix a issue..
Great people and honest
Will keep using them For service.

Called North America Honda for help
That was a waste of 30 mins of my life I won't get back.
I have spent 3 hours today driving to other dealerships because the Internet and phone calls are out of the equation at this point!
I have to say the dealer that worked on it is the only dealer in Indianapolis I will ever have work on my ridge!
The other 3 dealers are arrogant as hell and said it has to be rotors had to be installed wrong and they asked if I had them turned.. Listen ass clown they are brand new 4 different sets.
None of them listen to me which I can not stand!!!

I found a local shop that is intrigued by what I told them and guarantee me they will fix it or I won't have to pay!!!!

Oh yeah
I mention to the shop foreman at 2 dealers about the caliper bracket and the rubber brake line issues and the both said it has to be rotors!!!!
Arrogant mechanics!!!! Arrogance on a whole new level
