Car Forum / Hyundai Cars / December 200899 Elantra GLS w/ 4 Wheel disk and ABS: Brake Bleeding Question
I was wondering if anyone could tell me if I must use the Hyundai scan too to bleed the brakes or can I just start the car and run the engine t enable the ABS system? Also, if I am replacing just the 2 rear calipers, do I need to bleed al 4? Thanks - Message posted using http://www.talkaboutautos.com/group/alt.autos.hyundai More information at http://www.talkaboutautos.com/faq.htm Prepare the system and the new parts to transfer everything quickly. I there's a significant delay, you can pinch off the brake hose to preven excessive fluid loss. (This isn't typically acceptable, but for a DI repair, it's probably worse to allow the fluid level to get so low yo start getting air in the upper portion of the lines.) As long as you kee the fluid level in the master cylinder above the minimum level, you ca just bleed the two wheels where you did the work. Don't start the car either. Activation/self-test of the ABS unit can move the fluid around. Bleed the system like any other car, taking care to be certain the flui in the master cylinder doesn't get too low - Message posted using http://www.talkaboutautos.com/group/alt.autos.hyundai More information at http://www.talkaboutautos.com/faq.htm > Prepare the system and the new parts to transfer everything quickly.

A good tip to prevent too much fluid loss is to top the reservoir right up, and then put some cling-film over the opening, then if you can screw the cap back on, or else use a elastic band to hold the film. The vacuum over the top of the fluid then prevents it from leaking out. Jeff Thanks for the advice, I finally did get to this project and it worke well. I kept the hose end held high and lost a minimal amount of flui out of the hose or let the resevoir go low. The only thing I noticed i that when I drive, the first push on the pedal goes down further than th second or subsequent presses. It is solid, not "spongy", just more trave on the pedal. Not all the way to the floor, but it is noticeable. Th car has 127k miles on it. Could that be a master cyl. problem or do yo think there is air still in the line - Message posted using http://www.talkaboutautos.com/group/alt.autos.hyundai More information at http://www.talkaboutautos.com/faq.htm It's more likely that something is pushing the caliper piston in too far. Check to make sure that the pads aren't hanging up and that the pad shim aren't catching on the caliper - Message posted using http://www.talkaboutautos.com/group/alt.autos.hyundai More information at http://www.talkaboutautos.com/faq.htm |
