Sounds like your front brake dics are warped,It is a common problem with the 9r,especially those fitted with the six pot tockico calipers.Also check your brake calipers,the six pots tend to sieze pistons and need regular cleaning .

Try chaining fork oil.
check your forks for play.
check your pads for uneven wear.
also make sure the stearing head bearings are ok.
hope somethig helps.
could also be caused by the unevenly worn front tyre.

Rear brake pedal solid when operated via ABS


  • ABS - Anti-Lock Braking System And EBD -Electronic Brake-force Distribution In Plain English Posted by: Rohit Khurana March 1, 2010 in Automobile Technology Advertisement In continuation to the CarBlogIndia Technology Articles , today I will talk of one of the most talked about safety feature called the ABS And EBD. Again I will try to keep the language simple and human understandable (which non-engineers can also make some sense of), pun intended. What Is ABS ? Anti-Lock braking System system or ABS is a safety system which prevents the wheels on a moving vehicle from locking up(or cease while rotating) while braking. ABS offers improved vehicle control over dry and especially slippery surfaces by reducing the braking distance but it can also increase the braking distance in case of loose surfaces like snow, gravel etc. Ever since the invention of ABS, it has been evolving and the recent systems not only prevent wheel locking but also electronically control the front-to-rear brake bias, which we know as Electronic brake force system, Traction control system, Emergency brake assist or Electronic stability control. Working Of ABS ABS Advertisement When brakes are applied under heavy loads, the braking pressure becomes high resulting in heavy braking or in other words locking up of wheels. The ABS overcomes this by monitoring the wheel speed and releases pressure on each wheel brake lines in the form of rapid pulses switching between different brake lines. which prevent locking-up. Preventing lock-up under heavy braking helps the driver in maintaining control over the vehicle. In modern ABS an individual brake line is provided for each of the four wheel enabling different braking pressures for different road surfaces of the wheels. What Is EBD ? Electronic brake- force distribution system also called as Electronic brake-force limitation is an automobile brake technology that automatically varies the amount of force applied to each of a vehicle's brakes, based on road conditions, speed, loading, etc. EBD system is always coupled with anti-lock brake-force system. The most important function of EBD is to maintain vehicular control with variation in braking pressure applied to each wheel in order to maximize stopping power. Generally most of the weight of all vehicles is carried by the front end so the EBD ensures less braking pressure at the rear end to avoid skidding. But in some EBD's the distribution of braking pressure at the rear end is more initially when the brakes are applied before the effects of weight transfer comes into play. Working of EBD system An EBD is a subsystem of the abs and its function is to control the effective adhesion utilization by the rear wheels. this definition has been given by SAE in its technical paper no. #920646. Advertisement The Antilock brake force system releases pressure in different brake lines at the time of heavy braking to prevent locking-up. The action comes in the form of releasing pressure from the braking circuit when it detects extreme and rapid deceleration in any of the four wheels in order to make sure that the driver maintains control over the steering during panic or emergency braking. For example if the wheels of a vehicle are on snow as well as asphalt then in case of emergency braking the ABS will monitor the speeds and eventually the EBD system will release less pressure for wheels on snow and more pressure for wheels on asphalt to prevent wheel lock-up

I have a tl1000r and replaced front discs and pads and it has a shudder on hard braking


check the seating area on the wheels where the discs sit, so remove discs, and clean the contact area.

Derbi Terra 125 problem with the front brake: brake lever is very hard travels only few mm when squeezed (there's no regulation on lever) brakes are too sharp and sometimes brake pads dont free the...


Hello, Never dealt with motorcycles, still if you are sure that there is no air in the brake liquid, check whether the braking disk/pads are not hooked or (irregularly) worn-out. If this is not the case, replace the braking mechanism (the cylinder which pushes the pads), if too expensive, clean the old one and reassemble with new rubber parts. Please let me know whether I was able to assist.

Hi there, I have a 2001 EC200 GG and I'm finding the front brake weak and spongey. Is it generally the stock brake line or the pads that are the main problem, or something else? Cheers,


Hi, spongy brakes is usually from air in the system, only in really old bikes and poor quality brake lines will cause spongy breaks where the brake lines expand instead of full pressure being applied to the brake pads, very rarely will the brake pads cause spongy brakes (unless over heated), once you get rid of the sponginess you will get strong braking. Bleed your front brake system taking care not to let the master cylinder run out of fluid, this is the easiest and cheapest start, once all the air is out then you can work your way through, another good way of testing your braking system, but you need to be very careful doing this and make sure your brake lines are not hard or brittle, you can squeeze the brake line at certain spots (using a pair of brake line pliers), eg. squeeze after the master cylinder. if brakes spongy than your master cylinder needs attention, if brakes hard than your problem is further down the line, calipers etc. Hope this helps.

Does this model brakes front and rear at the same time when we press just front break ?


no ...you have a rear brake pedal to control the rear brake and the front is controlled by a brake lever which supplies 3/4 of all stopping power. Dont ever slam down on the rear brake pedal just apply it gradually.

Jumps out of gear when brake hard


The crunching noise is the slider gear going into the chosen gear. This is normal. The false neutral is likely just a case of shift pedal
adjustment. When braking hard you probably have your toe on top of the shift lever. If so then lower the front of the shift lever one or two notches. If your toe is below the shift lever then raise the lever one or two notches. THis adjustment should fix the problem.

Please rate this solution. Thanks!
