    LR4 Under Carriage

    I’m looking at buying an LR4 to replace my ‘98 Discovery. I noticed something on the under carrot that I haven’t seen before. Can anyone tell me what I have circled in the attached pic is and what that white hook is?

    head gasket debrief: lessons learned

    Thanks for all the input everyone. I've ended up using a combination of the options suggested and will follow up with what I found once I've wrapped everything up. Interestingly I didn't end up needed the swivel attachment, impact or otherwise. There was enough room on both of the back bolts for...

    head gasket debrief: lessons learned

    Thanks for the response. I'm not worried about spending the money and I've always been a proponent of the right tool for the job. It was just since in the Atlantic British video they simply said 16mm or 5/8 socket with a breaker bar and really glossed over any potential issues or challenges with...

    head gasket debrief: lessons learned

    I'm currently right in the middle of this project on a '98 D1 with the GEMS engine. I'm at the point of removing the head bolts and pulling the heads. Just a couple questions for all of you. First, is the reason everyone is referencing a 5/8 socket as opposed to a 16mm because 5/8 is...

    Brake Pedal Gradually Goes to the Floor

    I've been meaning to circle back to this and provide an update for a while. After suffering with this for awhile, but being able to drive the car due to the overall increase that in braking performance that the individual repairs provided, I noticed that I never seemed to be able to activate the...

    Brake Pedal Gradually Goes to the Floor

    Point taken and I agree with you on the fact that at some point, you just have to eliminate as best as possible and try parts. I'm just trying to pick my financial battles wisely on this car. Believe me, I'd love to just start overhauling with the idea that if it doesn't fully solve the issue...

    Brake Pedal Gradually Goes to the Floor

    Thanks for the suggestions. You are correct, I never get a firm pedal at standstill. I can pump it up to feeling initially firm after 4 to 5 long, slow pumps, but then it will just descend under constant pressure. I agree that this would normally leave the MC or the booster. However, I ruled...

    Brake Pedal Gradually Goes to the Floor

    I thought of that. Here my reasons for dismissing it, at least for the moment. Let me know if my reasoning is flawed and I've missed something. 1) I don't have zero brakes for a portion of the pedal travel and then achieve normal brakes later in the travel. In other words, it's not the "OH...

    Brake Pedal Gradually Goes to the Floor

    I finally got the chance this week to do the planned work. I replaced the pistons in seals in the remaining two calipers and installed stainless lines front and rear. Then I pressure bled all four calipers twice, going through roughly 1.25 liters of brake fluid in total. The rubber lines I...

    Brake Pedal Gradually Goes to the Floor

    Just an update. I received all the parts finally yesterday. The brake hoses were the last to arrive, shipping from NY. So, the work will begin this weekend: Replace rear caliper piston seals Replace front caliper piston seals Replace rear rubber brake lines Replace front rubber brake lines...

    Brake Pedal Gradually Goes to the Floor

    So an update from over the weekend. I had a long talk on Friday afternoon with the lead mechanic at Atlantic British. His assessment was as follows. 1) ABS air - Bleeding the ABS wouldn't be the issue. Any air introduced into the module through the standard bleeding of the bad master cylinder...

    Brake Pedal Gradually Goes to the Floor

    I've thought the same thing when driving it on flat ground and begun to question if there is an issue or it's in my head. However, if I have the car stopped on a decline, I'm praying for traffic to move before I creep into the car in front of me. In that case I need to continually apply more and...

    Brake Pedal Gradually Goes to the Floor

    Yes it does have the ANR3194 valve. That was mentioned in another thread as a possible issue. It's a little down the list of probable causes though as the symptoms don't match up. When they go bad, my understanding is it's typically accompanied by either lockup at the rear wheels under braking...

    Brake Pedal Gradually Goes to the Floor

    Thanks, I had already pulled a vacuum on the hose at the engine side. It was mentioned earlier in the thread though. The hiss was actually just a follow up confirmation of that reading. I believe I've ruled out the internal leak on the MC and you may be right on the ABS. More on both shortly...

    Brake Pedal Gradually Goes to the Floor

    I believe I've officially ruled out the MC. I'll post details on that shortly. I'm not experiencing fluid loss. I only brought up the servo as Rave's troubleshooting section for this assigns a sinking brake pedal issue, without visible leaks, to either the MC or the Servo. You may be right...

    Brake Pedal Gradually Goes to the Floor

    I pulled a vacuum on the engine side of the hose from the servo. It didn't produce a bunch of pressure, but held solid with no loss for 5 minutes. I also ran the car before pulling the new MC to check for leaks and there was an audible hiss when separating it from the servo. My understanding...

    Brake Pedal Gradually Goes to the Floor

    I guess some of this was buried in my long responses and overlooked. I have both a pressure bleeder and a vacuum bleeder as well as a scan tool. I just need to double check if it has the capabilit to cycle the ABS. I mentioned that the new MC was bench bled, but that air was most likely pulled...

    Brake Pedal Gradually Goes to the Floor

    Thanks. I'm not sure the ABS will engage with the current power the brakes are offering, but I'll give it a shot. Should the follow up bleed be done with the car running then? I've checked the rubber hoses and they show no signs of a leak. I figured expansion in those would account for a soft...

    Brake Pedal Gradually Goes to the Floor

    I thought about the air issue in the ABS block. I did bench bleed the new MC. However, prior to identifying the issue with the previous MC, some air was more than likely pulled into the system, as I was using a vacuum pump on the calipers and no fluid was coming out of the bad MC. The symptoms...

    Brake Pedal Gradually Goes to the Floor

    I'll give the full back story to this in order to try avoid wasting anyone's time with follow up questions. 1998 Discovery 1, with ABS. The initiation of the issue was after I installed new rear rotors and pads. Once everything was back together I couldn't get the calipers to bleed. I tried...
