Hi guys, I've got problems with the brakes (double disc on R65LS) and want to change to modern brakes. Any ideas of models that do not ask for many modifications on the bike ? Stay double or go to single disc ? Thanks for time

What's wrong with them, because the twin disk set up on the LS is pretty bullet proof if you fit braided lines and a decent set of disks. I've got a pair of EBC disks from Motorworks on mine and they make a massive difference especially in the wet.
-
I have not heard of any member successfully put other calipers, etc. on an R65 .
A few have tried, but I have not heard anything about a completed conversion .

Getting there!
I have amassed:-
A pair of matching disc rotors
A pair of Brembo 4-spot calipers from a K-bike
A 17mm Master cylinder kit.
Still to do.
Measure up and have machined a pair of stepped adapters to mount the calipers.
Sleeve my old 13mm master cylinder to 17mm and buy it a new reservoir
Have braided hoses made up.
Confession time.
Since I fitted a braided line to my single caliper F08 I am less enthusiastic about fitting the 4-spots to the R65. In fact, I've pretty much lost interest.
Of the gear I've accumulated, the genuine serviceable rotors would look nice on the R100 and the calipers are good spares to keep for my K-Bike project.
In fact I'd have to say that a stock system in good order, with perhaps the addition of braided lines (In my case I specified a braided line that has a black "rubber" outer cover so that it looks stock) works perfectly well and you would really have to have a serious need to go to more exotic brakes.
-
To which I forgot to add. I suspect that my experience mirrors that of many who have gone before - if you get the stock system working well, the percentage gain in engineering a "better" solution is more trouble than the gain to be had.
-
HI guys thanks for answer !
So I think i need to find a Repair kit to restore the stock callipers... I opened them yesterday evening and saw rust and dust... and they stayed stuck a bit on the rotor... a lot of noise etc...
Anyway it goes to my second question : Where i can buy repair kit for dual disc ? Any suggestion ?
Many thanks for time

Do you have Brembos or ATEs?
-
This is ATE sorry to forget to mention that !
-
This is ATE sorry to forget to mention that !
The ATEs will inevitably need new pistons as the manufacturer chose to use chrome plated steel for the pistons and aft more than 30 years the chrome plating will have broken down.
New stainless steel pistons are available at a price, or you can make your own if you have or have access to a lathe.
The seals are available and a suitably sized "Viton" O-ring can be substituted for the seal between the caliper halves.
Or you can buy new Brembo or Grimecia replacement calipers.

Motobins do rebuild kits for about £35 per calliper, but I'm sure there will be somewhere in Canada who sells them.

HI, I found that which including piston :

HI, I found that which including piston :
$134.95............................OUCH!!!!!!!
-
yes... if anyone has cheaper... (just because 134$ / each ;-)).... cost me 280$ including shipping... that's why i also consider swap to new technologies ;-)
-

I would spend $20 on the rubber parts and reuse the pistons and see what I had. If it didn't work out you can always spend the $300 dollars later.
-
yes well it's actually 29,95$ par set, need 2 for an LS... plus shipping : 74$.
I will try. Thanks !.
-
... plus shipping : 74$.
That's still a unsubstantial OUCH considering what you are receiving
I think my quick google returned some BMW "car" prices for ATE brakes. which are less costly
-
ordered. keep you in touch.

Those are for the single sided (i.e. single piston) ATE calipers fitted to the bigger bikes up to 1980. They will not fit the ATE opposed piston calipers in the R65

Hi guys, here is the calliper (right) same thing on the other side :-)

Flashback 51 years ago and memories of the raunchy XKE Jag that my late father cursed me with as a high school ride. Oh, the horror!

You can get brembo calipers new for about $100 a piece. Somebody posted a link to the site that sells them a little while back. It's a Moto Guzzi supplier, but the caliper is the same Brembo as our R65's.
I put new rubber in my ATE's but never replaced the pistons, I just cleaned them up. All has been working ok.
If I was going to go for a custom performance upgrade, I'd be looking at slotted rotors.

Chap I went to High School with had an e-type. The "cool" was somewhat diluted when you saw the holes int he floor and realized that the fuel tanks were shot and it was fueled by a jerry-can strapped to the back of the driver's seat.

Yea, but when Monte was in High School That Jag had to be practically new!!!
-
That Jag had to be practically new!!!
Judging from Monte's profile he was the class of 65". If he had it as a senior, couldn't have been more than 4 years old

Correct call, Joe. High school class of 1965 and college class of 1969. Last October wife and I attended the 50th HS reunion. Big crowd as there were over 1000+ students in my Senior class. Not all made it to the reunion, of course. Some didn't even get out of the 'Nam'
Anyway, my old man went through a "car stage" fueled by some doctor-prescribed, weight-loss drugs. Drugs made him absolutely bat s**t crazy. Uppers. Downers and In-betweeners...
The result was that in high school, I steered not only the Jag but an 1964 Corvette convertible and a Porsche 1600 Coupe... which my younger brother wrecked while I was working the summer as an archery instructor at a Boy Scout camp. Wanted to plant an arrow twit his stupid eyes, I did.
College days and the wheels were on my nickle. Triumph T100C and a string of then-cool Chevys.
Those were the days. Hell, they still are! ;D
