Title: New Master Cylinder front brake... Bleh!
Post by: pbureau69 on May 24, 2007, 04:32:55 PM
Well after having a "too hard to close the grip" on the front brake, I took it to the dealer, they bled it out and it was a little better, the tech most likely is the master cylinder that needs changing..

bike bandit lists the 05 model for 130$+ship, so I scouted out Ebay, and  I found one on ebay... but I am cautious, can someone <- 2000 GS500 owner advise if this looks like the one mounted on their bike ?

Suzuki lists 2 model of master cyllinders fornt brake system

2002-2007 part # 3016950-001 and pre 2002 as 510319-001

I have requested the seller for the part # (if he knows), but wanted to know if anyone reconized this part as a pre 2002 (I have an 05 and aside the color it is more "roundish" on the corners than the one on my ride.)

Help and input appreciated. (does it make a difference ??)

That is different than the one that is on my bike, I have a 2005.  So if you need the pre 2002 that should be the one.  Other than that i know nothing :laugh: :laugh:

Hes right, you wouldn't beleive the difference but get the 16x18 for a single caliper. Then change your caliper too.
I have a couple Nissin Radial masters that i replaced with Brembo GPs. Also have an axial brembo that would be an excellent upgrade if your interested. $80 w/ lever.

chuckles.. I need a master cylinder for daily driver, you guys are suggesting a brembo = basicaly racing equipment 3x the price of an oem unit... unless it lasts 10x the amount of time/usage, it aint worth the price to me.

Yeah, because it's not like having to stop or slow your motorcycle is a top priority, right?

I dont understand the reply, you saying the oem brake doesnt work properly or safely ?

I dont mean to be snobby, but 300$ for a master cylinder versus 130$ is a big jump in my budget right now
the oem brakes fine (I rarely go over 80MPH).

I dont and wont race-track the bike, so I dont see the resonning behind spending twice as much monies for something I wont use (ie I wont see a difference)

I would rather buy the oem and get a set of stainless steel lines (which I know make a difference for the $$ value) front and back...

I understand the brembo is the best there is... but I dont beleive I need it.

Sorry if I seem to be talking through my hat here.. but I dont beleive (unless you have concreate evidence) that the brembo (which from what I see people indicate I will need to upgrade my calipers next) are a saving value versus what I will use the bike for.

of course I will expect other to flame me, as I may have offended others in my commentary and this was not my intent.

Wait,wait,wait....why can't you just overhaul the master cylinder?
Title: Re: New Master Cylinder front brake... Bleh!
Post by: SmartDrug on May 24, 2007, 08:30:53 PM
I agree that the rebuild of the MC would be the best route and least expensive, but if you're going to drop the money to replace the MC, you may as well upgrade it.  Check eBay and see if there's a cheaper Brembo on there.  It's like anything related to vehicles, if you have to replace a part and an upgrade for just a little bit more, you should probably do it.  If you wreck the GS500 after learning how to ride proficiently, wouldn't you want to upgrade to a bigger/faster/nicer bike?  Same mentality, I'm not saying that you should agree with me, but I've been riding for a number of years and it has always worked for me.

okay let state for the understanding of the conversation for a moment that I am no inclined to
do the mechanical work on my own bike right now (I have and work on cars all the time but I know nothing about bikes)..

so that said, I rely for the time being on a friendly dealer mechanic for the work to be done.

I have not asked the dealer if they do overhauls of master cylinder, I am following the suggestion on the mechanic to simply change it (its currently catching in it way in and out and extremly tight to brake)

so I dont have the answer right now but I will ask the dealer if they do perform this and see the differential cost involved.


smartdrug : I see your point. I am just wondering how much longer does the brembo last, since it seems that from the mechanic at the dealership sort of stated that they "usualy (oem speaking here)" only last a few years and need to be replaced... if this is true of the brembo, then it is a loosing deal of cash for me.

First of all, if you only listen to one thing that I say in this thread it is this:  STOP GOING TO THAT DEALER

There's no way that the cost of the rebuild is even close to the cost of the new unit, it shouldn't take a mechanic more than an hour of labor plus parts, $100 max. 

There's also no way that a master cylinder only lasts a few years, that's preposterous.  I have about 100,000 worth of total mileage on motorcycles and have owned bikes ranging in years from 1974 to 2004 and have NEVER had ANY problems with a master cylinder, let alone had one fail completely to the point of not being able to be fixed. 

Rebuilding a MC isn't particularly difficult and as you said you're mechanically inclined, so I say give it a shot, if you realize you're in over your head, pretty much ANY mechanic will be able to put it back together for you and the cost shouldn't be more than an hour of labor.

The stock master is junk. It costs $130. A Brembo GP radial (cast) costs $250. A brembo replacement costs $80. Its better than stock (much) and its cheaper. Wheres the confusion? I have a stock master you can have for shipping.

The master cylinder on ebay looks just like the one I had on my 99 GS500 and at $40 seems like a good deal to me (the $15 shipping is BS though) I'd go ahead and place a bid but I wouldn't go above $50.

I had the stock brake setup with stock replacement pads on my bike for most of the time I owned it and I thought it was just fine, not great but fine. Just before I sold it though I put some HH+ pads on it and then it was amazing how much better the braking was. I'm sure the Brembo setup is better but I don't think it's worth the money when just putting on some good high performance pads can improve the braking so much.

I also think that you should look into rebuilding the master cylinder. I think that you basically just hone the cylinder, clean it out and then replace the seals. If you do any work on your cars it shouldn't be a problem. I've rebuilt brakes on cars but not on bikes, but I'm sure it isn't complicated.

alright ,

1) not many of you must have a wife :) (the married men wil understand the rest) which requires accounting and reasons to a woman that only sees the GS500 as a daily driver used to go to work.

2) if I did get the brembo gp brake (16x18? or 18x19?) this means I will also have to upgrade the rear master cylinder and upgrade my calipers ??

you mention 2 models of brembo maste cylinder a GP radial @ 250$ and brembo replecement (assuming oem replacment) for 80$? or am I miss understanding the meaning of that sentence. as for the oem for ship.. I may still take you up on it all depends on the answers I get from questions above.

no, dude, I will not listen to your statements, I stated this thread by asking about a replacement oem brake you replied; "just get top of the line brembo brake system, screw your budget,  just do it"

Telling someone that uses his motorcycle everyday (I ride for work alone over 500 miles a week), that never has worked on brakes (I said I worked on cars did not mean I ever did brakes)  to tell him try it out, if it doesnt work out bring it to the dealer, well if I do do it, and try do repair it myself and it fails WHEN I need it the most... what then genius?

I think I am humble enough to know when to leave a professional perfom the work for me, because  I value my life first (this doesnt mean I NEED a top of the line brembo brake system, this means I need a proper braking system that won't fail.)

I truly understand that oem is design by the cheapest parts and provide strict minimum required braking for the motorcycle.

I also understand that  upgrading is an appealing solution, but putting alot of money on the "racing brake system" is ridiculous.

now all this said, if I can find a "solution" that would upgrade the system in a moderate cash flow equation (and this includes dealer instalation no matter what ok?) then I will do it, otherwize OEM it will remain because... well it works.

I have been riding motorcycle on and off since 1982, so I understand brakes, I also understand I keep 3-4 car lenghs when I ride, so I always have "space" to brake.

now after this rant that neede to be said, I have QUESTIONS, if someone knows the answers, the please answer the questions, thanks

1) 16x18 as I understand it is for single disc, so is this all I need to "upgrade" (found one ;Brembo Master Cylinder -Radial Pump -16x18 -Brake $210.00 so this is getting more "affordable")

2) The oem model brake system comes with the "reservoir" attached, the brembo's seems to not have this, am I correct in assuming going the brembo route I will have to get "reservoir" and assembly to mount it somewhere on the front of the bike

3) Any other company aside brembo that would provide a upgrade to OEM that would be as cost efficient ?

Typical.

You ask how to do something, and you get arguments on whether or not you should do it, or whether you should be doing something else instead, and about your priorities and values for even asking the question...

For whatever it's worth, the MC in the listing does NOT look like the stock one on my '02, and the differences are as you described, "rounder" is descriptive. I guess it's an earlier version.

Ok f%$kstick, I have done nothing but try to help you here.  Chose to upgrade or not, what I said in the last post was simply that the dealer you were going to was not giving you advice that's on the level.  The cost of a rebuild IS NOT as much as a new MC, if they're saying that they just want to run you for more money.  If for whatever reason you didn't have the common sense to disclose that there's something seriously wrong with the MC and you DO need a new one, then in my opinion, you should spend the extra $100 and get something that might save your life (whether or not you listen to this is irrelevant, frankly I think you're a bit of a twat and really don't care if you end up a smear on the road). 

Hell hath no fury like a pissed off Triumph owner.

Oh, and don't misquote me again Buddha Loves You.

feel free to use the unsubscibe function the forum provides you so nicely so you dont have to continue to "try to help", since you dont care..

cheers mate, or do you like being called biatch?

PS: using "f%$kstick" (did I miss quite you this time?) or other demeaning words to make you feel better and show me up in front of a community of riders, is very sad. considering I asked a simple question to wich you help was to tell me to spend 300$ of a master cylinder, not answering the question was my first impression, then again english is not my first language, and perhaps I missed the double entendre of the sentence ?

anyways I see Ill get no real help here so Ill let the admin know they can kill this yhread as it has become a pissing match ... and nothing else.

OK,  basically any MC from a GS should work minor changes were made in the years but the handlebar diameter is the same so it'll still bolt up.  just find one that's cheap and that you don't mind the aesthetics of :thumb: :thumb:  you'd be hard pressed to find a weaker MC than the stock GS so any you find with the appropriate clamp diameter should be OK :thumb: :thumb:
