Don't cry cause it's over Smile cause it happened

Ontario, Canada


« on: May 25, 2012, 07:51:59 PM »

Howdy all.
I'm thinking my rear brake on my 2000 Interstate does not grip hard enough when I put the brake on.
I have installed new brake pads & lubed the pins.
I have bled out the old brake fluid & now have new fluid in the system.
If I push as hard as I can on the brake pedal, I cannot lock my back wheel up.
Any suggestions on where to look next?

If the pedal is adjusted right I think you have air in the lines.I can lock up my car tire easy.

I'll retry bleeding the air from the brake lines again but my "non-brake grip" was happening with the old fluid & still with the new fluid.
There has not been any alterations or changes to my braking system from the original factory settings which adds to my confusion.

I've never had a stong rear brake. Over the years, I've replaced the pads, rebuilt the caliper, replaced the brake lines with SS lines... Even replaced the master cylinder. I've learned to live with it.

How long have the new pads been on ?  It takes a little while for them to wear in to the rotor.

My rear brake locked up at the first of the year. Undecided I was surprised how much crud was on the exposed portion of the brake pistons and the amount in the bore. coolsmiley New O rings a little scotch brite and feels like brand new now. cooldude And no touble at all to lock it up with my darkside choice.

Thanks Bugslayer.
I'm starting to think like you.
I have replaced my front brake lines to SS & I honestly did not feel a big difference on performance. It is good to know the lines are new but the performance ................ no big difference from stock.
I do have a new rear SS brake line to be installed but I was hoping to rectify this rear brake issue before installing the new SS line.
Thanks for your response!

This definitely gives me something to think about (& possibly do).
Thanks for your response as I would love to be able to lock my rear brake up.

How well did you clean that rear caliper up, did you pop the pistons out and make sure there wasn't any globs of crud in behind them?

How many miles on the new pads?   You have a run in time with new pads.

If you have done all the above, I do believe I'd be pulling a master cylinder and making sure it is free of crud.    While you have the master cylinder off, ya might just as well install the SS lines.

Crud in the caliper, lack of fluid, and crud in the master cylinder are usually your things that give ya trouble,  OH YES, air in the line.

If ya pull the master cylinder and go through it, prime it before ya install it.   Prime means, get fresh fluid in all of the crevices of the master cylinder, you are getting the air out so it is easier to bleed later..

RJ.
I'll check the caliper for "crud" & probably get a rebuild kit for it.
I feel confident with bleeding brake lines so I think I'll check the other issues that you & the other fine people on the web site have mentioned.
Thanks for your response.

Remove the rear brake pedal and clean the rust/crud off the pivot pin and inside the pedal bore.....lube with a water proof grease and you are good to go....

Definitely agree with posts above about air and crud in system . My 2000 standard with 64000 miles on it seems almost to easy at times to lock the rear wheel up under emergency breaking.

What pads are you using ??  The local Honda shops only stock EBC and I didn't like them.. I prefer the originals..

Rio Wil and Bigbuck are on the right track, I believe.  It made a HUGE difference to my rear brake pedal effort when I disassembled, cleaned, and lubed the brake pedal pivot.

@ Patrick.
I am using EBC pads this time & used them last time also.
After checking everything today I am leaning towards agreeing with your opinion.
Thanks for posting!

I experienced the same thing you describe and found that the "Pin Bolt" was all corroded.

Check this link.  It is part #11.  It needs to be able to slide in and out of the caliper bracket. 

Remove it, check for corrosion and goober it up with grease.

Wrap some sand paper around a pencil and clean out the bore in the caliper bracket that the pin slides into.  It should be a "loose" slip fit.

@ Steve K.
I took this apart (again) today & re-lubed everything as you described. I was looking for anything not normal but failed to find anything obvious.
My brakes are no different than the were yesterday so I am now leaning towards the pads.
I did notice that the pads are not yet seated in 100% like "Custom1" had insinuated in his post.
I think I'll adjust my brake peddle up a hair as recommended by Art & Farther.
What are others opinions of EBC pads? Are they better once totally mated to the rotors?
We used to race stock cars & I remember some of the best gripping brake pads we ran were soft compound pads. They didn't last near as long as others but they gripped the rotors better for fasting stopping (faster stopping somehow doesn't sound right (lol)).
Thanks for posting Steve!
Some of this information is bound to help others as well.

There are different types of brake pads available from EBC.

Metallic, sintered, Kevlar, Organic, ceramic, etc.

They all have different stopping characteristics and wear factors.

Comparing is futile!

Not to nit-pick but Futile means "Having no useful result". I think you mean the the opposite of futile which is an "Antonym", which means "useful".
I do think like you Ricky-D & think it of utmost importancy to find the correct brake pads to suit our bikes.
This is where experience from others can save us all a lot of trial & error, not to mention money spent on this learning lesson.
Honda does have this figured out for us & sell this technology to us when we buy their pads. Their pads work!
Thanks for your post Ricky-D!

It is possible to get one of the caliper pistons stuck crooked in its cylinder.  At that point you have less than 50% of the braking strength because only one piston is pushing on the pad and that also will make the pad NOT be flush onto the face of teh rotor.  Use a flashlight and a mirror if you have to but get under there and make sure bilt pistons are sqarely pressed on the pad and the pad is swayre on the rotor and the same amount of piston is exposed fopr both pistons

Sorry Farther. I didn't realize the post count was so important to some but I must say .............. don't let my post count fool you  Wink.
I could have said "EBC Brakes makes only Organic and Sintered Brake pads" (from the EBC website), but I didn't.
I prefer(ed) Organic brake pads because of the way they can & are supposed to work. They are inherently “Softer”, easier on rotors and have a brake “feel” preferred by many riders, including myself.
Maybe I'm wanting to much from this bike but my brake feel is not where I personally want it.
After years of racing & enjoying brake sponsorships (financially), maybe I'm spoiled.
I also use a durometer on my tires because "rubber compound hardness" is something that has become important to me as this aids with better traction, especially when stopping & cornering. My motorcycle tire supplier "used" to tell me I didn't need new tires because I had lots of tread left, until I explained the logic to wanting soft rubber compound on my tires. I used to say to him "When they spin, you win".
Tire softening compounds ........................ boy can I talk experiences there too, both on & off the track, both with purchased tire softening additives & home made traction compounds.
All I want is to be able to stop quick, preferable without locking my brakes up. Maybe I just want to much.

Chrisj CMA.
Good point.
The piston movement did look good when I had the caliper out but as you know, things can work different when under actual working conditions.
I'll give this a look to see what I see.

Make sure the rotor is not warped. Simple run out check. If it is, that will open pads up while free running and give you much less braking authority when trying to use them.

Also ditch the ebc pads if you have a stock rotor. I've not found anything better then OEM on the valk (and they're darn good...something's up).

Rotor looks good.
I am surely agreeing with yours & everyone's opinion of sticking to stock pads.
