stuart147 Posted December 11, 2015 Share Posted December 11, 2015 I have been trying all afternoon to bleed the brakes on my Caterham all afternoon.I have had some work done on the front end that meant that the front calipers had to be removed. They are Hi-Spec 4 pot calipers and were new last winter. I have also had new front brake hoses made and these are fitted. While I had the car on axle stands, I took out the rear brake pads to check them and clean and grease the sliders.Today, I thought I would try to bleed them. I have bled them at least 4 times this afternoon using over a litre of new brake fluid. I started with the nearside rear then offside rear followed by nearside front and lastly, offside front.I have done them each time until no bubbles are present, but when I press the pedal, there is nothing there. The pedal goes straight to the floor.If it helps with answers, I am using an "Eazi Bleed" system.I have also done both inner and outer bleed nipples on the front calipers.Stuart Link to comment Share on other sites More sharing options...
SM25T Posted December 11, 2015 Share Posted December 11, 2015 Did you effectively drain the system by removing bits ? Sounds like you must have a lot of air in there. Stupid question .... are the bleed nipples on the top after the front calipers were refitted ? Link to comment Share on other sites More sharing options...
CharlesElliott Posted December 11, 2015 Share Posted December 11, 2015 Bleed using the pedal and not Eazibleed. It's not always very easy and I've had the same problem before using one. Link to comment Share on other sites More sharing options...
stuart147 Posted December 11, 2015 Author Share Posted December 11, 2015 Hi IanYou have me wondering now. Bleed nipples are very definetely on the bottom. Would it be possible for me to have put the calipers on the wrong sides? (Not the most technically aspired person).Hi Charles. Using pedal method not an option earlier today, but could be tomorrow.Stuart Link to comment Share on other sites More sharing options...
SM25T Posted December 11, 2015 Share Posted December 11, 2015 That's your problem. Air goes upwards. You are a plonker. Link to comment Share on other sites More sharing options...
SM25T Posted December 11, 2015 Share Posted December 11, 2015 Swap sides. Ezibleed will be OK. Link to comment Share on other sites More sharing options...
dan4182uk Posted December 11, 2015 Share Posted December 11, 2015 Use the gravity bleeding method - it takes a while but I've never known it fail.Just undo a bleed nipple and let it drip through a bleed pipe into a jar. Keep checking the master cylinder to make sure it doesn't drop too low and let air in. Do 1 corner at a time in the correct sequence.Probably takes 10 - 20 mins a corner, hence pro mechanics don't do it, but it's fool proof. You can also busy yourself with other stuff whilst it's at it, just keep checking the master cylinder level. Link to comment Share on other sites More sharing options...
CharlesElliott Posted December 11, 2015 Share Posted December 11, 2015 Still don't like Eazibleeds even if the calipers are on the correct sides. Link to comment Share on other sites More sharing options...
stuart147 Posted December 11, 2015 Author Share Posted December 11, 2015 Hi Ian.OOPS. I did say that I was not the most technically gifted Caterham owner.Will swap them tomorrow.I may use the gravity method and spend the 20 mins per side reading the build manual.Stuart Link to comment Share on other sites More sharing options...

OliverSedlacek Posted December 11, 2015 Share Posted December 11, 2015 It seems you have been pointed in the right direction. I usually use an eezibleed to do the initial bleeding as it's a very reliable way of pushing the bulk of the air out. I usually then finish off using the pedal as that seems to winkle out the last few bubbles. Link to comment Share on other sites More sharing options...
6speedmanual Posted December 11, 2015 Share Posted December 11, 2015 I find Gunson's Eazibleed very effective for flush through fresh fluid or for bleeding a system which has been drained for whatever reason, or freshly rebuilt. Just do not use the bottle reservoir to carry extra fluid into the system. If you get an air leak you will have a big mess! Link to comment Share on other sites More sharing options...
elie boone Posted December 12, 2015 Share Posted December 12, 2015 I change brake fluid in 1 h using less than 1 litre and all on my own but i use a compressor to put pressure on the system Link to comment Share on other sites More sharing options...
Vintageant Posted November 3, 2019 Share Posted November 3, 2019 None of these posts addresses how to bleed brakes with two separate master brake cylinders, one for the front brakes, the other for the rear brakes, obviously activated by the single brake pedal. If bleeding one, how is the pressure in the other closed system compensated? Link to comment Share on other sites More sharing options...
