ABS - Anti-Lock Braking System And EBD -Electronic Brake-force Distribution In Plain English Posted by: Rohit Khurana March 1, 2010 in Automobile Technology AdvertisementCarBlogIndia 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 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

Hi, I've heard of problems being caused with the ABS on BMWs because of battery problems. Sounds daft I know but it seems that unless the battery is 100% there can be many odd electrical gremlins. Easier to check than having to replace parts of the ABS kit. Good luck. Stan

use a manometer and balance both at idle using the big brass screw on each throttle body

not all of them

Under the tank

GIVE MIRROR A GOOD TUG ITS CLIPPED ON.THEN U WILL SEE THE FAIRING BOLTS

hi, i presume you mean earth, (neg) when you say ground. if this is the case have you tried looping the earth from the main beam side of the light, and afix it to the bulb holder on the low beam, is it that the unit is corroded around the earthing point, if this is the case you could simply fix a wire to the bulb retaining spring and see if the light works, this will be fine and work until you find areplacment light unit, make sure the earth wire canot come into contact with the live side by insulating it, hope this helps, paul

Hi! You surely have fuel flooding causing the bike to misfire. I strongly suggest that you replace the spark plugs and plug wires for better fuel burning. Hope this helps and thank you for using FixYa!

Well you can get a replacement by Google search or repair it or get a set of new ones

any good car parts shop should have cutout plastic mirrors, they will pass the MOT! or try your luck on
e-bay, try out glass shop,s ? they cut glass, so why not a mirror glass???

As the break pads wear it creates a greater volume(capacity) at the caliper piston/s.This causes the fluid in the reseviour to go down.(even though you have no leak) then you top it up & it will again reduce fluid level as the pads wear further.When the pads are replaced you are required to push the pistons back in to accomadate the new(thicker) pads. Before you push the caliper pistons in at brake pad change you will need to drain out some fluid(from the resivour) to stop the resivour from overflowing. This is typical of all hydrolic braking systems on both bikes & cars.Check the pads, If they are wearing this symptom is compleatly normal.

I'm guessing the TPS is bad, located on the Throttle body. If that doesn't do it check fuel pressure, have had fuel pumps cause that problem esp if the bike has been in accident, cracks the fuel pump inlet tube causing it to lose pressure.

You could have fried the electronics by jump starting the bike. BMW do not recommend jump starting. They only suggest a new battery. You will need a diagnostic check. You have probably fried one or two diodes that sit under the tank. Not too expensive but until check is done you cannot tell.

Headlight relays..1 for low 1 for high..These are most time under gas tank.Might be also located on battery box

if the rectifier has been changed and it is over charging the battery. The brain box is not sending the proper signal to the charging system. He would be correct in his findings. Check the charging system completely!

No, there is no need to balance the clutch. Just fit it and should work fine.

I have the standard trunk (supplied by BMW for 1150RT for a hefty price). Nice thing about it is that it fits nicely, has a backrest for the passenger and is very stable and strong. The poor thing about it is that it still will not fit a helmet. I suggest you also look at the GIVI trunk. I don't know how it will fit to the 1150RT, but I do know they look nice, are well made and large enough to accomodate a lot more thant the BMW trunk. By the way, how do you like your 1150? I love mine. If only I had more time to ride it.
