1982 GS750T: Warped Front Disc - Replacement Question...

[SamLack99]

01-front-brake-mot.jpg

Took Suzy for an MOT today (she's exempt, but I want to make sure she's safe after me wrenching on her for two years).

She failed on two points:

1. Headlamp not working on dipped beam (I'll see if a new bulb fixes that).

2. Brake grabbing severely front.

Fault two didn't come as a surprise. After fitting a new master cylinder, braided hose and brake caliper kit... I could feel the brake lever pulsing slightly when I pulled it.

My question...

Are there other motorcycles in Suzuki's '80s lineup that used a similar front disc?

The OEM part number is: 5922134550, and one is available at CMSNL for £245 + shipping.

I'd prefer to get something in the UK (to avoid shipping costs) and possibly avoid paying £245 for a replacement front disc that isn't warped <-- It doesn't have to be new.

Any advice from you, awesome GS owners, is very much appreciated.

Nice looking bike!

Looks like it's used on 12 different models. See at the bottom of this page.

You may want to measure thickness, and if above standard, get it ground flat.

EBC flys the Union Jack, I would see about getting a new rotor from them.

You have vintage style and standard style.

Now that's a proper motorcycle! Aside from mirrors, no unnecessary crap bolted on.
Owner: I agree with you. Less IS more.

If you absolutely must add accessories, feel free to choose from the following list:

Oil cooler
Steering dampener
Fork brace
Radar detector

This one is expensive, but looks to be worth the cost.

Local machine shops have been handy for me, truing bike brake rotors... Seems reasonable to ask one, or some, if they could help... Very nice looking bike. Good luck.

You guys really are the greatest.

Thank you.

Plenty to work with here and you've helped me to move forwards.

This is my current plan of attack:

1. I saw this at a breakers in the UK. I've contacted them to see if they can guarantee it isn't worn. At £32+postage - It could be a bargain

2. The one Nessim recommended looks perfect. At £147+shipping+import duty - It's expensive, but not as expensive as option 3

3. This one from CMSNL. If all else fails I'll bite the bullet and pay £243+shipping+import duty.

I'll keep you posted how it all works out.

Thanks again for the advice, much appreciated gentlemen =)
